                     Release Note for BCM5702 BOOT Code Firmware
                    ==================================================
Version 2.30:

      2. Fixed Rev. A2 Tx Scratchpad code loading problem.
      
Version 2.29:
      1. Support WoL Limit 10 speed

Version 2.26:
      1. Use default MAC address for entry 1 to 15
      2. Changed NVRAM corruption workaround algorithm

Version 2.25:
      1. Supports dynamic bootcode location (no longer need to be in a 
         fixed address in NVM).
      2. Implemented a new WOL scheme that requires drivers released
         after 07/17/02. Legacy drivers will continue to behave according 
         to the old scheme.
      3. Added support for 5702FE.
      4. Added power saving mode support.
      5. Minor bug fixes/enhancements for various corner cases:
         a. Fixed a bug where bootcode may fail to cut auxiliary power 
            when WOL is disabled on some NICs.
         b. Propagate EEPROM setting regarding WOL even on device reset.
         c. Fixed timing in propagating ASF configuration to driver.
         d. When enabled, restore WOL after loading and/or unloading PXE 
            or DOS driver.
         e. Fixed an LED problem with A2 LOM when ASF is enabled.
         f. Eliminated potential PHY access contention with driver.
         g. Added prevention on potential flash/EEPROM corruption if chip
            operates under an invalid voltage range.
         h. Fixed ASF configuration application misleading EEPROM content
            problem.
      6. Program all MacAddr Registers with the MacAddress in NVRAM

Version 2.24a:
      1. Fixed intermittent chip CPU crashing in auxiliary power mode 
         (CQ#3763).

Version 2.24:
      1. Propagate GPIO_1 usage to driver and corrected the usage
         in a VPD operation.
      2. Updated LED modes of operations.

Version 2.23:
      1. Exploited power state and pci power presence features supported 
         in A2.
      2. Included write protect of EEPROM for some LOM design.
      3. Increased the bootcode image size to 5kbytes (5120 bytes).
      4. Fixed pxe speed initialization (CQ#3488).
      5. Restored range check for VPD access.

Version 2.22:
      1. Support fastboot initiative.
      2. PXE and ASF no longer need to be mutually exclusive.
      3. Updated Ethernet@WireSpeed setup sequence.

Version 2.21:
      1. Added CRC checking before loading other firmware (e.g. ASF). 
         All speed LEDs will light up when CRC check fails.
      2. Added 5702FE and Ethernet@WireSpeed supports.
      3. Uses 0x16A6 as the new device ID in the boot image.

Version 2.19:
      1. Employed block read method when loading other firmwares (e.g. ASF)
         from non-volatile memory.
      2. Increased the bootcode image size to 4.5kbytes (4608 bytes). This 
         may have impact on boards that already have pxe or other firmware 
         programmed as they need to be reprogrammed.
      3. Added CRC checking before loading phase 2 bootcode. All speed LEDs 
         will light up when CRC check fails.
      4. Fixed a bug where a system cannot boot up if phase 2 bootcode is 
         corrupted.
      5. Fixed a bug where Windows does not wake up from standby due to 
         bootcode cutting off aux power.
      6. Eliminated flash interface reset as this may cause non-volatile 
         memory module to become out of sync.
   Note: PXE and ASF currently must be mutually exclusive. Enabling both
         may have an undesirable effect.

Version 2.18:
      1. Employed block read method when loading codes from non-volatile
         memory.

Version 2.17:
      1. Fixed a failure of loading PXE when WOL is enabled.

Version 2.16:
      1. Speed up the PXE loading (CQ#3108).
      2. Enable expansion ROM bit in phase one booting to avoid BIOS missing
         to load PXE when enabled.

Version 2.15: (A0 chip is no longer supported)
      1. Implemented two-phase loading to speed up the boot process.
      2. Firmware stops running after loading ASF to avoid interference.
      3. Cut off auxilary power when an OS turns off the device due to
         absence of driver.
      4. Use software arbitration support by the hardware when accessing 
         non-volatile memory.
      5. Included cold WOL support.
      6. Fixed a problem where the system fails to boot when both PXE and
         WOL are enabled (CQ#2977).
      7. Fixed a bug where the firmware did not clear VPD request after
         it is serviced.

Version 2.14:
      1. Moved multiple boot agent codes and fixed uninitialized variable bug.
      2. Updated default subsystem device ID.

      3. Embedded version string into the executable binary.
      4. Support multiple boot agents.
      5. Set LED to PHY mode when card first receives auxilary power.
