Burning gPXE into Broadcom BCM57xx-based cards
<referback>This page is part of the ROM-burning tutorial.</referback>
The Broadcom Diagnostic Utility set allows you to update the expansion ROM images in Broadcom BCM57xx gigabit network cards (and rebranded Broadcom cards such as the HP NC7771).
Preparing the ROM image
Copy the gPXE ROM image (e.g. bin/0e1100ca.rom) to a FAT-formatted floppy disk or USB drive.
Preparing the tools
Download the Broadcom Diagnostics Utility from http://www.broadcom.com/docs/driver_download/570x/B57udiag-10.53.iso. Burn this image to CD using your favourite CD burning method.
Burning the gPXE ROM
Boot from the CD and select the following sequence of options:
- “Continue to boot FreeDOS from CD-ROM”
- “Install to harddisk using FreeDOS setup” (which won't actually install anything to your hard disk)
- The language of your choice
- “Run FreeDOS from CD-ROM (return to command prompt)”
You should now see an X:\> prompt. Type:
cd \b57udiag b57udiag -ver
You should see something like:
X:\>cd \b57udiag X:\B57UDIAG>b57udiag -ver **************************************************** Copyright(c) 2000-2007 Broadcom Corporation Broadcom NetXtreme User Diagnostics 10.53 (07/27/07) **************************************************** C Brd:Rv Bus PCI Spd Base Irq EEP MAC Fmw Configuration - ------- ------- --- --- ---- -- ---- ------------ ---------- ------------- 0 5703:B0 05:04:0 32 33 FC50 11 128k 00110AE99C0B 5703-v.235 WMp,auto 1 AC1K:B5 05:00:0 32 33 FF7F 9 4k 00095B1C29D9 2.5 auto
This shows the list of Broadcom cards in the machine. Select the card that you wish to burn gPXE into, and identify its card number (from the left-hand “C” column in the listing).
To burn gPXE into the card, type:
b57diag -c 0 -pxe c:\0e1100ca.rom
where -c 0 specifies the card number of the card that you wish to burn gPXE into, and c:\0e1100ca.rom is the path to the gPXE ROM image on your FAT-formatted floppy disk or USB drive. You should see something like:
X:\B57UDIAG>b57udiag -c 0 -pxe c:\0e1100ca.rom **************************************************** Copyright(c) 2000-2007 Broadcom Corporation Broadcom NetXtreme User Diagnostics 10.53 (07/27/07) **************************************************** C Brd:Rv Bus PCI Spd Base Irq EEP MAC Fmw Configuration - ------- ------- --- --- ---- -- ---- ------------ ---------- ------------- 0 5703:B0 05:04:0 32 33 FC50 11 128k 00110AE99C0B 5703-v.235 WMp,auto 0 5703:B0 05:04:0 32 33 FC50 11 128k 00110AE99C0B 5703-v.235 WMp,auto Updating PXE-UNDI16 code (length = 59908 bytes ) ...

Reboot the machine and enter the BIOS setup. You should see gPXE show up as an option in your BIOS's boot selection menu.
Congratulations on successfully burning gPXE into your network card!
