Version 7.15 Aug 29, 2003
   1. Problem:
             The network icon may intermittently disappear when changing driver
             properties when PowerMon is loaded and QOS is enabled.
             The driver was incorrectly restarting phy auto-negotiation excessively
             causing the driver to take too long to report link up to the operating
             Added code to only restart phy auto-negotiation when there is a change
             in the state of ReverseNway.

   1. Request:
             Add "volatile" modifier to SendPass and DpcPass driver variables to
             prevent the compiler from optimizing references in ia64 and amd64
             Added "volatile" modifier to SendPass and DpcPass driver in ia64
             and amd64.

Version 7.14 Aug 28, 2003
   1. Request:
             Add support for multiple mac addresses on the same nic.
             Added registry keys and custom OIDs to allow third party software
             to configure the nic with multiple mac addresses.

Version 7.13 Aug 25, 2003
   1. Problem:
             The crc error counter for 5700 and 5701 was not getting zeroed
             out when T3_OID_RESET_STATS_COUNTERS is called.
             The crc error counter for 5700 and 5701 was not getting zeroed out
             when the OID call is made.
             Added code to zero out the crc error counter for 5700 and 5701 when
             T3_OID_RESET_STATS_COUNTERS is called.

   2. Problem:
             The retail WinXp32, WinXp64, AMD64 drivers were being compiled with
             incorrect compiler flags.
             The build environment was not configured correctly.
             Corrected the retail build environment of the affected operating
             systems to use the correct compiler flags.
             Executables will be slightly smaller.

Version 7.12 Aug 20, 2003
   1. Problem:
             Driver Verifier complains about a possible deadlock problem.
             The driver was holding a spinlock during Ndis calls in the send
             Removed spinlocks during Ndis calls in the send path.

   2. Problem:
            System fault under heavy network load (verifier C4_31)
            The driver may incorrectly use spin locks at ISR level
            Remove all calls to acquire spin locks from the ISR.

   3. Problem:
            Improper use of spin lock in shutdown handler
            The driver is using a spin lock in the shutdown handler
            Remove calls to acquire spin locks from shutdown handler

Version 7.11 Aug 15, 2003
   1. Problem:
             The OID_GEN_RCV_OK statistic incorrectly included receive
             overrun frames.
             The driver needs to subtract the number of receive overrun
             frames from the values reported by hardware.
             The driver subtracts the number of receive overrun frames from
             the value reported by hardware before reporting the statistic
             to Windows.

   1. Request:
             Improve bit error performance of 5703A0 and 5704A0 when used
             with long cable lengths.
             Program the phy's ADC and Gamma registers to more optimum settings.

   2. Request:
             Improve serdes drive levels on 5704.
             Programed the serdes config registers with the values recommended
             by the hardware design team.

Version 6.82 Aug 5, 2003

   1. Problem:
             Incorrect operation after PHY loopback test. Reported against 
             Linux configuration. 
             PHY register 0x18 is not programmed properly after running the external
             loopback test.
             Changed the value written to PHY register 0x18 from 0x480 to
             the correct value 0x400 (after external loopback test).						 

   2. Problem:
              Flow control does not function (CQ8181).
              LM_SetupCopperPhy() does not always program the flow control
              when the link comes up.
              Program the flow control in all code paths when the link comes up.

   3. Problem
              Idle cycle fix in 5704 B0 has side effects on certain HP/CPQ

              This hardware fix is not enabled in this version.

Version 6.80 July 29, 2003
   1. Request: 
               Add support for external loopback with loopback plug.

               Added new requested media type values for external loopback.


   2. Request: 
               Enable hardware fixes in 5704_Bx parts for known erratas.

               Added code to driver init routines to enable hardware fixes in
               5704 B0 silicon.  See 5704 errata for more details info about
               the changes/fixes in B0 silicon.


   1. Problem:
              AMD Solo System intermittently blue screens when installing driver for 5704

              The driver is executing pageable code at high IRQ level (UM_Initialize()).  

              Isolated the code executing at high IRQ level to a non pageable routine.


Version 6.69 July 9, 2003
   1. Problem:
              In Windows Win98SE: System cannot go into sleep mode when "wake up frame" is set

              Win98SE expects WakeOnLan capability of  MagicPacket  as well  as  WakeUpFrame
              during its query of  OID_PNP_CAPABILITIES; even if device Advanced Properties is set to
              WakeUpFrame only.  

              Added setting of MagicPacket support during handling of OID_PNP_CAPABILITIES.

              This change does not affect actual WOL function as specified in the Advanced Properties
              of the device, and only allows Win98SE systems to go to Standby mode.

   2. Problem:
              5700BX will stop processing packets under heavy loads.

              A CoalesceNow workaround for stale status block information on the 5705 was
              causing the 5700BX to hang.

              Qualified the CoalesceNow workaround to be applied to only the 5705.


Version 6.68 June 19, 2003
   1. Problem:
              The adapter doesn't drop link when WOL is disabled and the driver
              is disabled.
              If WOL is enabled and the adapter is linked at 1gb when the driver
              is put into low power state, the adapter does not re-acquire link
              at 1gb when the driver resumes.

              A typo in v6.65 of the driver was causing the driver to assume that
              ASF is always enabled.
              A change in v6.65 of the driver was causing the driver to not restart
              link autonegociation on resume.

              Corrected typo causing the driver to assume that ASF is always enabled.
              Changed the restart autonegociation routine to take into account the
              changes made in v6.65

              These changes affect all adapters in all versions of Windows.

Version 6.67 June 13, 2003

   1. Request: 
               Increment version number for revision control purposes.

               Changed version number from 6.66 to 6.67


Version 6.66 June 02, 2003


   1. Problem:
              CQ7927: System locks up when driver is unloaded on 5700/5701 with ASF.

              A workaround that is not applicable to the 5700 and 5701 related to
              nvram accesses was being executed which caused an access to a invalid

              Qualified the asf and nvram access workaround to be executed on only
              non 5700 and 5701 parts.

              This change only affects 5700 and 5701.

Version 6.65 May 31, 2003


   1. Problem:
              CQ7874,7873: Cannot get link after disabling power saving mode
              with ReverseNway. Cannot get link after changing from 100mb switch
              to 10mb hub.

              There was a corner case in the ReverseNway logic that was causing
              the phy not advertise correct capabilities when ReverseNway is
              disabled while the control suite has the driver suspended.
              There was a corner case in the ReverseNway logic that was causing
              the to not be reset properly when the phy lockup errata was executed.

              Corrected corner cases so the phy advertises correct capabilities to
              it's link partner.

              These changes only affect those platforms that have ReverseNway enabled.

   2. Problem:
              CQ7914: 5700BX fails to pass traffic while running 2c_Simultaneous
              WHQL tests.

              A change in the 6.60 driver to address an errata on the 5704 inadvertently
              broke an existing fix for the 5700_BX small fragment errata. The bug was
              causing the driver to run out of coalesce buffers when run on 5700_BX

              Corrected code so the driver will properly handle small fragment coalesce
              buffers on 5700_BX devices.

              This change only affects 5700_BX devices. Other devices will not see any
              change in behavior.

Version 6.64 May 20, 2003


   1. Problem:
              CQ785207: Device is Yellow Banged out after disable/enable of the

              There was a race condition in the halt cpu routine in which the
              halted cpu could still be holding the NVRAM arbitration bit.
              This was preventing the driver from reading the configuration
              information from the NVRAM and caused the driver to unload.

              Added check in the halt cpu routine to see if the halted cpu is
              holding the NVRAM arbitration bit.


Version 6.63 May 20, 2003

   1. Enhancements:


   1. Problem:
              CQ7807: Loopback- - Mac test fails

              The driver was not correctly configuring the 5705 for mac loopback
              if the device was linked at 10mb.

              Changed code to correctly configure the device when linked at 10mb.


   2. Problem:
              CQ7827: System will freeze on shutdown when linked at 10mb half.

              The phy was getting powered down during reset.

              Changed code to not power down the phy during reset.


Version 6.62 May 15, 2003


   1. Problem:
              CQ7656: Driver get yellow bang on 5788.

              A check for the device/bond id was detecting the 5788 as an
              unsupported device and therefore was causing the driver to unload.

              Removed the check that was causing the driver to unload.


   2. Problem:
              CQ7798, CQ7799: ChkInf found errors in the inf files.

              Typos in the inf files.

              Corrected the inf files.


   3. Problem:
              The workaround for the phy lockup errata was not being applied to all
              versions of the 5703 and 5704.
              There was a check for previous revisions of 5703 and 5704 that was
              incorrectly carried over from a previous errata.

              Removed check for specific versions of the 5703 and 5704 for the phy
              lockup errata.


   1. Enhancements:
              CQ7795, CQ7800: 1000 Full Duplex option in adapter advanced properties
              for all inf files.

              This option is suppose to be present in only inf files for specific
              OEMs. Removed 1000 Full Duplex option from files that are not applicable.


Version 6.61 May 14, 2003


   1. Problem:
         CQ7777: Some of the OID tests are failing in win98me

              Added parameter checks in the OID processing are not
              valid in all cases. These were added in rev 6.54

              Removed the checks, they do not work for all cases as implemented.


   2. Problem:
         The driver did not restart autoneg on Fast Ethernet only parts when resuming
         from hibernate or standby.

              This was originally intended behavior. However the driver needs to
              restart autoneg on resume due to phy lockup errata.

              During resume check for Fast Ethernet only capable parts and 
              restart phy auto negotiation.


   1. Enhancements:
              The following OEM device ID's are not in the inf files.

              Added OEM device ID's


Version 6.60 May 12, 2003


   1. Problem:
               Fixed problem with link getting dropped when shutting down Windows
               when using a 5703/2 with old versions of bootcode when OOB WOL is
               The bootcode was not properly passing configuration information to
               the ndis driver.
               Modified the ndis driver to read the configuration information directly
               from NVRAM.

   2. Problem:
               System bluescreens with random bugcheck values on .Net with 5704.
               A bug in the 4gb errata workaround with LSO enabled was causing buffer
               overruns which would corrupt system memory and cause random bugcheck values.
               Allocated static double copy buffers for use with LSO and 4gb aligned

Version 6.59 May 5, 2003


   1. Problem:
               CQ7664: New HP device IDs need to be added.
               Added HP device IDs to NIC .inf

   2. Problem:
               CQ7521: Mac loopback test is broken with fiber devices
               UM_AutogRetryTimerFunction() calls LM_SetupPhy() during test
               Added LM_REQUESTED_MEDIA_TYPE_LOOPBACK condition to call to 

   3. Problem:
               The driver will intermittently load with a zero mac address.
               The shared memory area that contains the mac address was not properly
               initialized when the nic is in certain low power modes.
               Read the mac address from the NVRAM and not shared memory.

Version 6.58 May 1, 2003


   1. Problem:
               Laurel PING -t gets 20-30% 'request timed out' on both ports (CQ7586)

               Fiber phy setup is being performed every half second because we are using
               the autoneg bit as a condition. This bit is not set when the fiber switch 
               is not doing autoneg.
               Only look at the autoneg bit when autoneg was successfully completed.

   2. Problem:
               Hardy having link status inconsistency (CQ7550)

               Fiber Phy was not programmed properly.
               Changed the NDIS code to behave like the Linux code.

Version 6.57 April 29, 2003

   1. Problem: 
               When the phy is poweredd down via BMAPI the network icon in the system
               tray does not always show link down.
               Race condition between the trying to indicate link down to the operating
               system and the phy reset routine trying to indicate link up to the operating
               Corrected logic error to remove race condition.
   2. Problem: 
               The OID OID_GEN_TRANSMIT_QUEUE_LENGTH does not support 64bit queries.
               The code did not support 64bit queries.
               Corrected code to support 64bit queries.

   3. Problem: 
               Updated phy workarounds for potential intermittent link problems for 5704/5705.
               Not applicable.
               Not applicable.

Version 6.56 April 18, 2003
   1. Problem: 
               The phy workaround implemented in 6.55 was not properly qualified to
               be applied to only 5704.   
               An 'if' statement was missing when the code was checked in.
               Added 'if' statement in routine with 5704 phy workaround to properly
               qualify the workaround.

Version 6.55 April 17, 2003

   1. Problem: CQ #7454, CQ #7559, CQ #7352, CQ #7453, CQ #7500, CQ7469
               Incorrect and intermittent WakeOnLan behavior on 5788. System waking up when
               not configured to wake and system not waking up when configured to wake.
               Ndis driver was not allowing enough time for the bootcode to complete
               execution of it's second phase of boot before communicating WakeOnLan
               configuration information to the bootcode.
               Extended max delay for the driver to wait for bootcode to complete execution
               by 60ms.
               Driver unloads will take 60ms longer to execute.
   2. Problem: 
               Ndis Driver takes too long to initialize
               The ndis driver had a lengthy delay routine are part of phy initialization
               The wait loop was qualified so it only applies to 5700 and 5701. Those parts
               were observed to require this delay.
               Ndis driver initialization should be faster by more than 20ms.

   3. Problem: 
               5704 intermittently will not auto-neg link at 1gb.
               The phy has a errata that requires the driver to check if the dfe is
               locked up.
               Added dfe lockup check routine as part of the phy reset routine.
               Slightly higher cpu utilization when the cable is first disconnected.

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

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

    Disallowed receiving packets bigger than 1514 but less than 1536 when
    jumbo frame is not enabled.

    Maximum jumbo frame size was changed from 8000 to 9000 bytes in b57nt4.hlp.

1.26        01/02/01

    Changed the way DPC is being serialized.

    Increased the maximum jumbo frame size to 9k.

    Added code to reset the PHY and wait for link during initialization.

    Fixed 1c_ofld.tst failure when only the transmit checksum is enabled.

    Modified the default interrupt coalescing parameters in b57w2k.inf and

    Restore PCI subsystem and subvendor IDs on a reset.

1.25        12/22/00

    Added support for the B1 silicon.

    Fixed no link up interrupt.

    Fixed intermitten W2k system hang on boot up when there is no cable
    connected with Netbuei and Nwlink protocol installed.

    Modified b57w2k.inf to enable WOL and TX checksum offloading capabilities.

    Improved driver performance.

1.24        12/16/00

    Fixed problem with link functuation when coming out of hibernation mode.

    Fixed possible memory leak due to transmit packet descriptor not being
    freed up when the driver unloads.

    Cosmetic changes to oemsetup.inf and b57w2k.inf.

    Added code to check for subsystem vendor Id.

1.23        12/11/00

    Fixed an intermitten system crash when unloading the driver on a busy

1.22        12/09/00

    Fixed 1c_gtime failure when forcing 10mb full duplex on an HP 2424M switch.

1.21        12/07/00

    Shorten "Link Selection" items in b57w2k.inf and oemsetup.inf.

    Added software workaround to recover from link mismatch settings.  For
    example, the link partner is forced to 100mb and the adapter is forced
    to 10mb.

1.19        12/04/00

    Replaced "Driver" with "Controller" in b57w2k.inf and oemsetup.inf.

    Fixed a very intermitten MAC and PHY loopback failure.

1.18        12/01/00

    Removed TxMtu configurable parameter.  Now the user only has to configure
    RxMtu to enable jumbo frame support.

    5401 B0 silicon was not being resetted when the 1gb link went down.  The
    reset is required as software workaround for the 5401 errata.

    Driver will now restore a couple of PCI configuration registers after
    a reset.

1.17        11/29/00

    Added the ability to configure jumbo frame parameter in the b57w2k.inf.

    Fixed driver reporting wrong link status after reboot when forcing
    link speed on both sides.

    Fixed failure in MAC loopback test.

1.16        11/28/00

    Updated the 5401 tap power-management script.

    Removed the busy polling for link when unplugging the cable.  The polling
    period was too long and it was causing BASP to drop some Chariot

    Removed support for A0, A1 silicon to reduce code size.

1.15        11/26/00

    Fixed intermitten system lock-up on shutdown when WOL is enabled.

    Multicast table was never cleared which was causing the intermitten
    failure in 2c_rmult.

    5401 reset on link down should occur only when the current speed is 1gb.

    Reduced driver load/unload time which will eliminate the 1c_gtime warnings.
    However, these warnings may still occur when WOL is enabled.  This is due
    to the driver waiting for auto-negotiation to complete before completing

1.14        11/22/00

    Added a software workaround for the 5401 to prevent it from locking up
    when the cable is unplugged during transmission.

    All the LEDs now indicate their corresponding link speed.

1.13        11/21/00

    Fixed problem with TCP connections dropping when running Chariot in
    10/100mb mode.

    Fixed problem with the adapter being disabled after exiting from the
    standby mode in Windows 2000.

    Fixed problem with the adapter not entering into wake-up mode when

    Ignore TX checksum parameter for B0 silicon.

1.12        11/18/00

    Added WOL support for Windows 2000.

    Fixed intermitten lock-up in 10mb mode.  Shadowed several MAC registers.

    Fixed PHY register read problem.  Occasionally PHY register read returned
    an incorrect value.

    Default TaskOffload and FlowControl parameter to off.

0.9         11/10/00

    Added MagicPacket support.

    In v0.8, whenever the driver detects a link mismatch, it will recover
    by switching to auto-negotiation mode.  This version does not have this
    recovery mechanism.

    Write the link settings to the EventLog after the driver has initialized.

    Fixed 1c_gtime failure when forcing line speed.

0.8         11/03/00

    NdisPacket allocated by the driver did not have the protocol reserved
    area which could cause system crash.

    Added a better handshaking mechanism with the firmware.

    Fixed the 2m_addres test.

    Added Compaq Hot Plug PCI support in oemsetup.inf.

    The MAC was not properly setup to operate in half duplex mode.

    Modified the driver to receive maximum sized VLAN packet without using
    the Jumbo receive ring.

0.7         10/30/00

    Fixed problems with forcing line speed.  

    Added checksum offloading capability.

    Fixed several issues with the Ndis test.  The following test should
    pass now:  1c_ofldn, 2m_load, 2m_misc, 2m_addre.

    Added support for IBM hot plug.

0.6         10/22/00

    Fixed lock-up that occurs when running the Ndis stress test.

    Fixed system crash when stopping the driver on an A1 silicon.

    Minor changes in b57nt4.hlp.

    Fixed problems with PHY loopback.  Added support for MAC loopback.

    Added a vendor specific OID for changing the MAC address.
    Tested VLAN tagging and 802.1p priority packet.

0.5         10/17/00

    Added a timer routine to periodically program the hardware to update
    the status block and generate an interrupt.  This is necessary because
    with A0, A1, B0 silicon, under certain condition, the host will miss

    Disable PCI NWI by default.

    The send producer index is written twice.  This is a bug in the A0, A1, B0
    silicon in which chip will miss the mailbox stimulus.

    Added tx/rx PAUSE frame negotiation with link partner.  Modified b57w2k.inf
    to allow the user to configure rx/tx PAUSE frame independently.

    Fixed VLAN bug.  The driver was retrieving VLAN tag from the wrong offset
    in the miniport reserved area.

    Added jumbo frame support.  The user must manually modify the registry
    parameter to enable this feature.  "RxJumboDescCnt" must be changed
    to some value greater than 20 but less than 256.  This value determine
    the numbe of receive buffers to allocate for jumbo frames.

    Modified oemsetup.inf and b57w2k.inf to default "DisableAutoNeg" to 1,
    which will disable auto-negotiation advertisement when selecting a
    particular line speed.

    Added a help file for b57nt4.sys driver.

0.04        10/02/00
    Added support for link change detection via PHY interrupt as oppose to
    having the MAC poll the PHY.  PHY interrupt processing can be enable
    via "UsePhyInterrupt" registry parameter.  Default is "auto-polling".

    Miscellaneous modifications oemsetup.inf and b57w2k.inf.  Also fixed
    driver update issues with oemsetup.inf.

    Added delay before the driver is unloaded to prevent W2K from detecting
    the card as a different device.

    Fixed the deserialized driver to queue outgoing packets when there is no
    more packet descriptors left.

0.03        09/21/00
    Modified reset and halt routines to handle shutdown more robustly.  Some 
    systems will not recognize the board after a warm boot.  This version
    of the driver should fix this.

0.02        09/09/00
    Initial release for the A1 silicon.
