Version 8.12 February 10, 2005
------------------------------

   1. Problem:
               CQ #12121: Not able to map to server after driver is loaded.
               Driver doesn't work with Hamilton/HTLE A1 or newer devices.

      Cause:
               ASIC IDs for Hamilton and HTLE A1 or newer have been changed
               from 5 to 9 and 8, respectively.

      Change:
               Changed Driver to accomodate the ASIC ID changes.

      Impact:
               None.


Version 8.11 January 13, 2005
------------------------------

   1. Problem:
               CQ #11735: DOS ODI16: Unable to connect to Server with Hamilton
               board. Driver does not work with Hamilton devices.

      Cause:
               There is an ASIC problem where the device misdetects parity
               errors. This causes DMA engine to halt after first DMA write
               transaction.
  
      Change:
                Added software workaround by disabling device's parity
                detection logic.

      Impact:
               None.

   Notes:
   ========

   1. The download firmware in use is v1.16.0 to align with PXE. Only impact

   ============

   1. Request:
               Added support for Baxter family devices (BCM5752,BCM5752M)
               and Hamilton family devices (BCM5714,BCM5714S,BCM5715
               BCM5715S).

      Change:
               Add support for Baxter and Hamilton hardware.

      Impact:
               None.
   
   Notes:
   ======

   1. No release for v7.74-v8.09. Adjust version number for new NICs support.


version 7.73  December 01, 2004
-------------------------------

   1. Problem:
               CQ #11439: 16bit ODI driver failed when tested with RPL/PXE.

      Cause:
               The fix for CQ #11357 using INT 21h leaves system that boots
               up remotely using RPL/PXE in an unknown state.

      Change:
               Driver scans DOS memory block to determine if TCPIP stack is
               resident.
               
      Impact:
               None.


version 7.72  November 22, 2004
-------------------------------

   1. Problem:
               CQ #11357: DOS ODI with NSUP using TCPIP has poor transmit
               performance.

      Cause:
               Driver transmits packets out of TCP/IP sequence, which
               causes the Protocol to delay and retransmit as of CQ #7650
               of the B44.ODI.

      Change:
               Driver waits for the previous transmission to be completed
               then process the current transmit request when using with
               TCPIP stack.
               
      Impact:
               None.


version 7.71  November 11, 2004
-------------------------------

   1. Problem:
               CQ #11271: Driver to install up on device with cable
               connected.

      Cause:
               Driver already have logic to detect and load up on the
               device that has cable connected. However, the time to
               detect the cable was not significant to allow some switches
               to finish its link establishment process. So, the driver
               determines there is no link prematurely then load up on the
               first found device.

      Change:
               Driver continuously senses for 3 seconds before determines
               there is no link.
               
      Impact:
               Driver load time will be a multiple of 3 seconds per NICs on
               multiple NICs system that has only one cable connected.


   Enhancements:
   =============

   1. Request:
               CQ #11117: SerDes Pre-Emphasis Enhancement Request.

      Change:

               None.

   2. Request:
               CQ #11194: To check for out-of-range Busnum, Devnum, and
               Funcnum entries in NET.CFG.

      Change:
               Driver checks for out-of-range Busnum, Devnum, and Funcnum
               entries in NET.CFG and display messages accordingly.

      Impact:
               None.

      Impact :
               None.

 
version 7.69  August 26, 2004
-------------------------------

   1. Problem:
               When The ODI Driver is unloaded other devices that
               shared the same IRQ are disabled.

      Cause:
               When The ODI Driver is unloaded, it masks off its own
               IRQ which could also be shared with other devices. This
               effectively disables those devices.

      Change:
               Driver preserves and restores the interrupt mask value
               when it loads and unloads.

      Impact:
               None.


version 7.68  August 25, 2004
-------------------------------

   1. Problem:
               CQ #10827: Systems with Adaptec CERC SATA 1.5/6ch hang
               when unloading Broadcom NIC Driver.

      Cause:
               Driver restores the flags register without preserving it
               when its unloads.

      Change:
               Driver preserves the flags register and restores it
               accordingly.

      Impact:
               None.


version 7.67  August 19, 2004
-------------------------------

   1. Problem:
               CQ #10794: When DOS ODI driver is unloaded, it does not
               restore the interrupt mask bit.

      Cause:
               Driver does not restore the interrupt mask bit when its
               unloads.

      Change:
               Driver restores the interrupt mask bit when its unloads.

      Impact:
               None.


version 7.66  June 25, 2004
-------------------------------

   1. Problem:
               CQ #10470: Broadcom Manufacturing Diagnostics
               Hanging on Interrupt Tests on Santa Fe after the ODI
               driver loads and unloads.

      Cause:
               Driver enables Tag Status Mode (BIT 9) in the Miscellaneous
               Host Control Register (Reg 0x68). This bit does not get
               clear on Diagnostics' reset.

      Change:
               Driver clears this bit when its unloads.

      Impact:
               None.

   2. Problem:
               CQ #10478: ODI driver loads with invalid BusNum/DevNum
               (0 and -1).

      Cause:
               Driver does not detect these values as in-valid.

      Change:
               Driver aborts with 0 and -1 BusNum and DevNum.

      Impact:
               None.


version 7.65  June 18, 2004
-------------------------------

      Impact :
               None.


version 7.63  May 25, 2004
-------------------------------

   1. Problem:
               CQ #10190: ODI driver crashes system with invalid
               BusNum/DevNum in NET.CFG.

      Cause:
               Driver calls function with invalid values.

      Change:
               Driver aborts with invalid BusNum and DevNum.

      Impact:
               None.

   Enhancements:
   =============

   1. Change:
               Add support for a test device.

      Impact :
               None.

   Notes:
   ======

   1. The Lower Module is aligned with PXE v7.5.15.


version 7.62  May 12, 2004
-------------------------------


   1. Problem:
               CQ #9968: Unable to use BusNum and DevNum parameters to load
               driver when BusNum is greater than 15.

      Cause:
               Driver compares the user's input with the device's value using
               only the lease significant byte.

      Change:
               Driver compares with word size.

      Impact:
               None.

   2. Problem:
               When disconnect/reconnect using 3 pairs cable, NDIS2 driver
               takes about 34-35 seconds to get the link and causes the
               system to suspend during this link re-establishment period.

      Cause:
               When the 3 pairs cable is reconnected, its takes approximately
               17 seconds until the driver detects the link change activity.
               The driver is then resets the PHY, which causes another 17
               seconds before the NIC could gets the link back. Driver polls
               for the link during the link re-establishment.

      Change:
               Driver resets the PHY as when its detects the cable is
               disconnected. Driver does not poll for link during link
               re-establishment.

      Impact:
               None.

   Enhancements:
   =============

   1. Change:
               Add support for device was previously removed per CQ #9955.

      Impact :
               None.


version 7.61  April 23, 2004
-------------------------------

   1. Problem:
               CQ #9955: Need to remove support for an untested controller.

      Cause:
               The controller has not been tested for this release.

      Change:
               PCI Device ID for non-production controller was removed 
               from driver.

      Impact:
               None.


version 7.60  April 19, 2004
-------------------------------


   1. Problem:
               Driver might not detects link if RJ-45 cable has broken
               pairs with Shasta family devices.

      Cause:
               Ethernet@WireSpeed is not enabled and Driver doesn't wait
               long enough before declaring no link.

      Change:
               Driver to enable Ethernet@WireSpeed and waits longer before
               declaring no link.

      Impact:
               Driver might takes longer to load when cable is not present
               and/or loading on multiple NICs system.

   2. Problem:
               On certain corners, Bit-Error-Rate(BER) was higher than
               desired when cable length was 70m or less.

      Cause:
               PHY related issue.

      Change:
               Applied the workaround for higher BER problem.

      Impact:
               5705 Family and later.

   3. Problem:
               CQ #9814: Unable to unload driver with LSL /f.

      Cause:
               Driver hooked its Timer Tick through DOS.

      Change:
               Driver hooked its Timer Tick using LSL's Support 
               MLIDSUP_SCHEDULE_AES_EVENT.

      Impact:
               None.

   4. Problem:
               CQ #9873: When the NIC is configured in Shasta Mac Mode,
               the Speed LED stuck at 10 Mbps after the cable was moved
               to different switches that has different speed set up.

      Cause:
               Driver did not update the setting of the MI Status
               Register properly when speed is changed.

      Change:
               Driver update the setting of the MI Status Register 
               according the changed speed.

      Impact:
               None.

   Notes:
   ======

   1. This code base was merged with v7.11 to carry over its fixes of
      problem 1 & 2.

   2. The Lower Module is aligned with PXE v7.5.13.

   =============

   1. Change:
               per CQ #9792: Add new banner.

      Impact :
               None.


version 7.58  April 05, 2004
-------------------------------


   1. Problem:
               Shasta shared traffic/link LED mode doesn't work. 

      Cause:
               There is a bug in Shasta A0/A1 (MAC block) where shared
               traffic/link LED mode doesn't work correctly.

      Change:
               Driver to program the device to use this feature provided
               by the PHY block.

      Impact:
               None.

   Enhancement:
   ============

   1. Request:
               LED mode is now programmed only by the boot code firmware.

      Change:
               Driver doesn't program LED mode for Shasta family devices.

      Impact:
               None.

   Notes:
   ========

   1. The Lower Module is aligned with PXE v7.5.12.

      Impact :
               None.


version 7.56  March 16, 2004
-------------------------------


   1. Problem:
               CQ #9582: Link problems when forcing speeds on Cisco
               Catalyst switch. 

      Cause:
               Driver forces selected speed before the PHY reset process
               is completed.

      Change:
               Driver waits for the PHY reset process to be completed
               before forcing the selected speed.

      Impact:
               None.

   Notes:
   ======

   1. This code base was merged with v7.10 to carry over its fixes but w/o
      Banner change.


version 7.55  February 26, 2004
-------------------------------


   1. Problem:
               System hangs while loading NDIS2 on BCM5751/21 A1 silicon
               during a cold boot.
 
      Cause:
               BCM5721/51 A1 or newer silicon has fixes so that PCI Express
               link is maintained after a GRC reset. Driver enabled this fix
               while issuing GRC reset without realizing it was previously
               disabled.

      Change:
               Driver to enable this fix before issue GRC reset.

      Impact:
               None.

   Enhancements:
   =============

   1. Request:
               Enable H/W fixes for BCM5721/51.

      Change :
               Enable Rx FIFO fix.

      Impact :
               None.

  Notes:
  ======

   1. The Lower Module is aligned with PXE v7.5.9.


version 7.54  February 19, 2004
-------------------------------


   1. Problem:
               System generates an NMI whenever driver issues software 
               GRC reset.  

      Cause:
               BCM5751/21 A0 silicon device does not generate Completion TLP
               associated with the last Configuration Write to the chipset. Due
               to this abnormality, the chipset will generate a NMI as fatal
               completion timeout error.

      Change:
               Added a software workaround in the driver so that core clock is
               slowed down to 6.25MHz which will give some time for the PCI-E block 
               to send back Completion TLP to the chipset. 

      Impact:
               None.

   2. Problem:
               After a GRC reset, link is dropped and therefore retrained with 
               link partner. Link retrain might take up to 500ms. If device is
               accessed before link retrain is complete, system might lock up
               or encounter fatal errors. This change only applies to BCM5751/21 
               (PCI express family) revision A0 devices.

      Cause:
               BCM5751/21 A0 silicon.

      Change:
               Changed chip reset routine to delay 500ms after A GRC reset.

      Impact:
               None.

   Enhancement:
   ============

   1. Request:
               Add additional LED modes for BCM575x/2x family.

      Change:
               Changed to support new LED modes.

      Impact:
               None.

   2. Request:
               BCM5721/51 A1 or newer silicon has fixes so that PCI Express
               link is maintained after a GRC reset.

      Change:
               Driver to enable this fix so that PCI express link doesn't drop.
               
      Impact:
               None.

   3. Request:
               Banner change to NetLink (TM) for BCM5788 device.

      Change:
               Driver displays NetLink (TM) when load up on BCM5788 device.
               
      Impact:
               None.

version 7.53 January 10, 2004
-------------------------------

   1. Problem:
               CQ #9091: Driver will not load when PXE is enabled and Unable to
               load/unload DOS ODI driver multiple times.

      Cause:
               Driver uses of register during initialization to determine if the
               NIC is in used by another instance of the driver was contaminated
               when PXE is loaded.

      Change:
               Driver uses other register that is not conflict with PXE.

      Impact:
               None.

      Cause:
               Driver initializes the use of NIC's core clock BEFORE enable the
               PCI access, result with the loop count of zero for the Delay
               routine.
      Change:
               Driver initializes the use of NIC's core clock AFTER enable the
               PCI access.

      Impact:
               None.


   2. Problem:
               CQ #9050: DOS ODI driver displays incorrect link speed with ASF
               enabled.

      Cause:
               Driver did not shut down ASF.

      Change:
               Driver shut down ASF during initialization when detects ASF is
               enabled.

      Impact:
               None.

  Notes:
  ======

   1. This code base was merged with v7.09 to carry over its fixes.


Version 7.51 November 26, 2003
-------------------------------

   1. Problem:
               CQ #8944: ODI driver is not picking up the right MAC Address.

      Cause:
               Missing one MAC register read due to source code condition
               compilation.

      Change:
               Included complete read of the MAC address registers.

      Impact:
               None.

   2. Problem:
               ODI driver failed Read/Write stress test when there are more than
               one UUT.

      Cause:
               Driver picked the wrong MAC address (CQ #8944) and uses the same
               MAC address resulting duplicate MAC address on the LAN.

      Change:
               Included complete read of the MAC address registers.

      Impact:
               None.

   3. Problem:
               ODI driver takes 20-30 minutes to bind protocols when used with
               5751 NIC.

      Cause:
               Delay value was too large for the current delay routine, which
               uses the system's timer tick as one unit (54ms).

      Change:
               Driver uses NIC's core clock to calculate number of loop for the
               delay routine to achieve approximate 1us as one unit.

      Impact:
               Driver will initializes faster.


Version 7.50 November 21, 2003
-------------------------------

   Enhancement:
   ============

   1. Request:
               Add full support for BCM5751/21-based NICs/LOMs (PCI Express
               interface).

      Change:
               The Lower Module is ported from PXE v7.5.2 (since PXE v6.2.4
               ported at ODI v6.05).

      Impact:
               None.
   
  Notes:
  ======

   1. No release for v7.12-v7.49. Adjust version number for new NICs support.


version 7.11  April 19, 2004
-------------------------------


   1. Problem:
               Driver might not detects link if RJ-45 cable has broken
               pairs with Shasta family devices.

      Cause:
               Ethernet@WireSpeed is not enabled and Driver doesn't wait
               long enough before declaring no link.

      Change:
               Driver to enable Ethernet@WireSpeed and waits longer before
               declaring no link.

      Impact:
               Driver might takes longer to load when cable is not present
               and/or loading on multiple NICs system.

   2. Problem:
               On certain corners, Bit-Error-Rate(BER) was higher than
               desired when cable length was 70m or less.

      Cause:
               PHY related issue.

      Change:
               Applied the workaround for higher BER problem.

      Impact:
               5705 Family and later.


version 7.10  April 09, 2004
-------------------------------


   1. Problem:
               CQ #9582: Link problems when forcing speeds on Cisco
               Catalyst switch. 

      Cause:
               Driver forces selected speed before the PHY reset process
               is completed.

      Change:
               Driver waits for the PHY reset process to be completed
               before forcing the selected speed.

      Impact:
               None.


   Enhancement:
   ============

   1. Change:
               Driver displays NetLink (TM) when load up on BCM5788 device.
               
      Impact:
               None.


   2. Change:
               per CQ #9792: Add new banner.

      Impact :
               None.


version 7.09 December 18, 2003
------------------------------


   Enhancement:
   ============

   1. Request:
               Banner change.

      Change:
               Sign on banner and display messages same as DOS NDIS2 driver.

      Impact:
              None.


version 7.08 November 08, 2003
------------------------------


   1. Problem:
               CQ #8804: Using PowerQuest v5.5 with multicast caused system to hang.

      Cause:
               Driver's Interrupt Service Routine was continuously re-entered due to
               the system's interrupts was re-enabled after the Update Status Block
               Flag was cleared and before PCI interrupt INTA# gets cleared. This
               blocked the remainder of the ISR to be executed.

      Change:
               Driver clears the PCI interrupt INTA# right after Update Status Block
               Flag gets cleared and before the system's interrupts get re-enabled.

      Impact:
              None.


version 7.07 October 24, 2003
----------------------------


   1. Problem:
               None.

      Change:
               PCI configuration data register (0xCFC) does NOT needed to be
               preserve in Driver's PCI configuration Read and Write subroutines.
               Removed the preserve of PCI configuration data register (0xCFC)
               that was put in v7.05.

      Impact:
               This would remove unnecessary I/O cycles every time the driver
               accesses the PCI configuration area.

   2. Problem:
               CQ #8554: DOS ODI-16 driver hangs during process of loading
               the driver after booting up using PXE Remote Boot up on Intel PDK
               server.
 
      Cause:
               Driver preserved and restored the PCI configuration data register
               (0xCFC) and the PCI configuration command register (0xCF8) around
               the NIC's Initialization routine. When booting up from Intel PDK 
               sever in this case, data in the register 0xCFC and 0xCF8 had
               such values that when they were restored it would mask off PCI
               interrupt INTA# output.

      Change:
               Removed the preserve and restore of the PCI configuration data
               register (0xCFC) and the PCI configuration command register
               (0xCF8) around the NIC's Initialization routine to leave the
               Miscellaneous Host Control Register with the value where the NIC's
               Initialization routine was set at.

      Impact:
               None.

   3. Problem:
               When attempting to force the 100/Full or Half with LineSpeed
               forced in the NET.CFG file while the switch is set to AutoNeg.
               The driver's sign on message indicates "forced", but the switch
               reports 100 Full when it should reports 100 Half.
 
      Cause:
               Driver configured the NIC properly but on some switch;
               it's required a "line drop" to update the duplex status.

      Change:
               Driver toggled the SuperIsolate bit to simulate a "line drop"
               that allows the far-end to adjust to the forced speed and duplex.

      Impact:
               None.


   Enhancements:
   =============

   1. Request:
               None.

      Change:
               Displays "forced" when LineSpeed and Duplex were forced in NET.CFG.

      Impact:
               None.


version 7.06 October 21, 2003
----------------------------

   Fixes:
   ======

   1. Problem:
               CQ #8628: DOS ODI-16 driver hangs during process of loading
               the driver after booting up using PXE Remote Boot up on 3Com DABS
               PXE server.

      Cause:
               Driver's ISR calls the ISR chain whether or not the interrupt is
               generated by the NIC or not.

      Change:
               Driver's ISR calls the ISR chain ONLY when the interrupt is
               NOT generated by the NIC.

      Impact:
               none.


Version 7.05 October 03, 2003
----------------------------

   Fixes:
   ======

   1. Problem:
               CQ #8554: DOS ODI-16 driver hangs during process of loading
               the driver after booting up using PXE Remote Boot up on Intel PDK
               server .
 
      Cause:
               PCI configuration data register (0xCFC) was not preserve in Driver's
               PCI configuration Read and Write subroutines.

      Change:
               Driver preserves PCI configuration data register (0xCFC) also.

      Impact:
               none.


Version 7.04 September 09, 2003
----------------------------

   Fixes:
   ======

   1. Problem:
               Driver does not display message:
               "The B57 driver has been successfully removed." after
               finished unloading.

      Cause:
               Driver terminated prematurely before displays the message.
               This was introduced since v6.11.

      Change:
               Driver displays the message then terminate.

      Impact:
               none.

   2. Problem:
               (CQ #8434) When perform stress LOAD/UNLOAD, the system
               hangs after 161 to 1700 iterations.

      Cause:
               Driver unloads without checking for TSR installed above
               itself.

      Change:
               Driver unloads after checking for TSR installed above
               itself.

      Impact:
               none.


Version 7.03 September 05, 2003
----------------------------

   Fixes:
   ======

   1. Problem:
               DOS ODI 16 cannot unload while in "Full Size" mode with 5700 A
               and B step devices.

      Cause:
               Driver does not de-allocate the extra memory that was required
               to run in "full size" mode with 5700 A and B step devices.

      Change:
               Driver releases the extra memory when shutdown.

      Impact:
               5700 A and B step devices.


Version 7.02 August 29, 2003
----------------------------

   Fixes:
   ======

   1. Problem:
               (CQ #8403) DOS ODI 16 - Cannot pass traffic on fiber NIC.

      Cause:
               Lower Module required to instruct firmware (v1.14.0) to use
               AUTONEG or 1000Mbps FULL for fiber NIC.

      Change:
               Lower Module commands firmware to use AUTONEG or 1000Mbps FULL
               for fiber NIC.

      Impact:
               Fiber NIC.


Version 7.01 August 29, 2003
----------------------------

   Fixes:
   ======

   1. Problem:
               Driver uses zero MAC address on 5700 & 5701-based NIC/LOM
               when reads it from Serial EEPROM.

      Cause:
               Serial EEPROM routine has a bug, which causes MAC address in
               the serial EEPROM cannot be read correctly.

      Change:
               Fixed serial EEPROM driver so that MAC address can be read
               correctly.

      Impact:
               None.

  Notes:
  ======

    1. This is a "theoretical problem" only.


Version 7.00 August 26, 2003
-------------------------

   Fixes:
   ======

   1. Problem:
               (CQ #8241) Driver causes divide over flow if IRQ is disabled
               in BIOS.
     
      Cause:
               Driver still loads when BIOS provided with an invalid IRQ.

      Change:
               Driver only loads when BIOS provided with IRQ value between
               2 and 15.

      Impact:
               none.

   2. Problem:
               Driver uses same MAC address for both ports on 5704 NIC when
               reads it from NVRAM.
     
      Cause:
               Driver uses the same offset for both ports.

      Change:
               Driver uses correct offset for the second port.

      Impact:
               none.


   Enhancements:
   =============

   1. Request:
               Improve bit error performance of 5703AX and 5704AX when used
               with long cable lengths.
      Change:
               Program the phy's ADC and Gamma registers to more optimum 
               settings.
      Impact:
               None.

   2. Request:
               Improve Serdes drive levels on 5704s.

      Change:
               Programed the serdes config registers so that SerDes' drive 
               transmission level is 1.2V. This modification was made in the
               driver download firmware v1.14.0.
      Impact:
               None. 

  Notes:
  ======

   1. Firmware v1.14.0 is used in place of v1.9.0 was used since DOS ODI v6.07.
   2. No release for v6.13-v6.99.


Version 6.12 August 19, 2003
-------------------------

 Fixes:
 ======

   1. Problem:
               (CQ #8289) PowerQuest could not establish connection.
			
      Cause:
               The driver had disabled net.cfg parsing for debug and it had
               not restored the code for production driver. Protocol 802.2
               was the default, but Ethernet_II frame type was required.
            
      Change:
               The debug driver code was taken out.

      Impact:
               All adapters.

   2. Problem:
               (CQ #8158)  When repeatedly booting the system, loading 
               the DOS ODI driver, connecting to a Netware server, and 
               rebooting, the system will intermittantly have a problem
               connecting to the server.

       Cause:
               The phy initialization code would sometimes finish before
               properly completing.	
            
       Change:
               The delay time was increased to ensure completion. 

       Impact:
               All adapters.


Version 6.11 August 13, 2003
-------------------------

   Fixes:
   ======

   1. Problem:
               The driver could only be loaded and unloaded sequentaily
               a fixed number of times depending on the number config.sys
               files= command was set to.

      Cause:
               The initialization code was interfering with DOS by overwriting
               the FILES = stack space.
                  
      Change:
               Driver init code now uses a seperate stack.

      Impact:
               Change is on all adapters.

   Enhancements:
   =============

   1. Request:
               Support 5704 b0.

      Change:
               Updated code to support 5704 b0.

      Impact:
               None.


Version 6.10 July 14, 2003
-------------------------

   Fixes:
   ======

   1. Problem:
               (CQ #8117) Factory test process locks-up after executing
               VLM.exe with DOS ODI.

      Cause:
               A stack problem in the interrupt enable code in the driver. 
                  
      Change:
               Interrupt enable code stack fixed in driver. No other changes.

      Impact:
               No noticable impact.

   Notes:
   ======

   1. v6.09 is Engineer release for testing purpose only.


Version 6.08 May 22, 2003
----------------------------

   Fixes:
   ======

   1. Problem:
               (CQ #7839) (CQ #7840) When connected to a hub, a
               momentary disconnect will cause a loss of network
               connection until the driver is reloaded.

      Cause:
               The NIC does not generates PHY Change Interrupt after
               the PHY Reset when the link is first lost.

      Change:
               Driver preserves and restores Auto-negotiation
               advertisement register after the PHY Reset.

      Impact:
               None.

   2. Problem:
               User tries to force 1G.

      Cause:
              Driver allows parameter to be set.

      Change:
              Driver will perform Auto-negotiation when LineSpeed is
              set to 1000.

      Impact:
               None.



Version 6.07 May 12, 2003
----------------------------

   Fixes:
   ======

   1. Problem:
               (CQ #4981) Running PERFORM3 test with a 5703S causes the
               system to either hang or reboot.
               (CQ #7448) When using DOS ODI and ODINSUP running NetBEUI
               protocol, some systems may not be able to use remote drives.
               (CQ #7449) Stressing a SUT running Netbeui on ODINSUP may
               eventually hang the machine.
               
      Cause:
               The timer function corrupted the stack.

      Change:
               Assigned correct stack label to timer function.

      Impact:
               None


   2. Problem:
               (CQ #7683) Intermittently slow with BCM5704 Serdes/
               CIOBE Serdes.

      Cause:
               Firmware (v1.8.0) performs autonegotiation when link is
               up and hardware autonegotiation logic indicates AUTONEG
               is completed.

      Change:
               Changed the firmware (v1.9.0) so that it will not
               perform autonegotiation when link is up and hardware 
               autonegotiation logic indicates AUTONEG complete.

      Impact:
               5704 Serdes/CIOBE Serdes.


   3. Problem:
               (CQ #7718) Link detection intermittently fails when ASF
               is enabled. 

      Cause:
               Contention with ASF firmware polls for PHY registers
               during PHY reset routine with PHY lockup Work-Around.

     Change:
               Driver stops ASF firmware before accessing PHY during
               initialization. 

      Impact:
               When ASF is enabled, link establishment will take twice
               as long when ASF is disabled.


   4. Problem:
               (CQ #7648) Fixed a problem where dynamic 10/100 or
               10/100/1000 PHY auto-neg advertising based on GPIO2 state
               might not work correctly and appears to take a long time
               to re-establish the link. 

     Cause:
               This issue was introduced when the PHY lockup workaround
               was added. This problem only occurs on the platform where
               the GPIO2 state is used for dynamic PHY auto-neg.

      Change: 
               Changed the PHY lockup workaround code so that it restores 
               AUTONEG configuration.

      Impact:
               None.

   5. Problem:
               (CQ #7706) Fixed a problem where driver reports
               a forced LineSpeed when there is no cable detected.

     Cause:
              Driver was not checking for link when LineSpeed and Duplex
              were forced.

      Change: 
              Driver checks for link always.
 
      Impact:
               None.


   Enhancements:
   =============

   1. Request:
               Added Keywords to force LineSpeed and Duplex in NET.CFG file

      Change:
               Recognize LINESPEED and DUPLEX keywords and force the speed
               and duplex mode accordingly.

      Impact:
               None.


   Notes:
   ======

   1. Problem #2 to #5 are fixed carry over from NDIS2's Lower Module.



Version 6.06 April 29, 2003
----------------------------

   Fixes:
   ======

   1. Problem:
               The PHY lockup problem described in v6.05 Fix #3 below
               theoretically can affect other PHY cores in 5703 and 5705. 

      Cause:
               A Hardware bug in the PHY core. Probability of lockup is
               extremely small.

      Change:
               Expanded the lockup detection and recovery code to include
               5703, 5704, and 5705. Also changed the driver to do a 
               PHY reset on link down.

      Impact:
               5703 and 5704.


   2. Problem:
               Driver cannot detect a link change status
               when the driver first initializes without cable attached.

      Cause:
               When the driver initializes without a cable attached, the
               driver does not enable the Link Change Status Interrupt.

      Change:
               Enable Link Change Status Interrupt during driver 
               initiation even when cable is not attached.

      Impact:
               None.


   3. Problem:
               When the cable is disconnected and reconnected,
               its takes longer than expected to re-establish link.

      Cause:
               When the cable is reconnected, the driver runs a 
               Setup PHY function that has a long delay.

      Change:
               Reduce the delay time in Setup PHY function.

      Impact:
               None.


Version 6.05 April 25, 2003
----------------------------

   Fixes:
   ======

   1.  Problem: 
               (CQ #7380) Driver is not functional with 5700 A and B step
               devices due to the smaller internal memory model being used by
               downloading exclusive firmware for the 16-bit(DOS) drivers.

      Cause:
               The exclusive firmware for 16-bit(DOS) drivers prevents
               the factory loaded firmware from providing a work-around 
               for the 5700 A/B devices as described in the device errata.
   
      Change:
               Added 5700 support.
               When the driver is loading on a 5700 A/B device, it will
               not download the exclusive firmware for the 16-bit(DOS)
               driver. It will allocate an additional 48KB of memory.
               
      Impact:
               For 5700 A/B support, the memory footprint of the driver
               will be ~83KB.


   2. Problem: 
               (CQ #6467) Intermittently, the 5704S Fiber NIC cannot pass
               traffic when connecting to a 3COM SuperStack 4900sx switch
               after a system-soft reset.
      Cause:
               Auto-Negotiation timing.
   
      Change:
               The fix was in the firmware that gets download during
               initialization.

      Impact:
               5704S Fiber.

 
   Enhancements:
   =============
   1. Request: 
               Added support for dynamic 10/100 or 10/100/1000 phy
               auto-neg advertising for certain platforms.

      Change:
               Added a check for the state of GPIO2 during link change
               events and adjust auto-neg capability advertising
               accordingly.

      Impact:
               None.

   Notes:
   ======

   1. The code base for this version is from v6.04 with the 5704 PHY
      lock up work-around and zero MAC address fixes in v6.03.2
   2. The Lower Module is ported from PXE v6.2.4.


Version 6.03.2 April 18, 2003
-------------------------
 Fixes:
 ======
   1. Problem: (CQ #7280)

	Cause:  Phy Locks up when continual resets to phy occur.
                Note:This a very rare condition and may not be
                      reproducible.
                  
    Change: Check the phy after each phy reset to determine if lockup
			occurs. Additional phy reset clears lockup.

	Impact: The fix to this problem should not be noticeable. 


Version 6.03.1 April 18, 2003
-------------------------
Enhancements:
=============
   1. Request: Removal of all 5704/CIOBE support.
	       
      Change:  Code for 5704/CIOBE detection was removed in the driver.
			   Check for zero MAC ADDRESS included to syncronize with 
			   other driver code.

      Impact:  Driver will not detect or load on any 5704/CIOBE device. 
			   Please note that non-5704 support may contradict other documentation.
			   No other impact.
