 +=== Alternate strategy booting MEMDISK from GRUB ===
 +Additional notes from a user:
 +In this instance, I could not use a 3com 3c90 to pxe boot, at all, it would just hang, even though I flashed from 4.00 to 4.30 using memdisk, I still could not pxe boot, so somehow I found myself a newer mbaflash.exe
 +This was all done on Debian.
 +Download a newer mba for the 3com cards (4.31)
 +  curl -O ftp://​ftp.hp.com/​pub/​softlib/​software1/​ob656/​ob656en/​3cmba431.exe
 +Extract with 7zip:
 +  7z x 3cmba431.exe
 +The first 32 bytes of firmware.img is just the COPYDISK header, so skip it
 +  dd if=firmware.img bs=32 skip=1 of=dos.img
 +If you can boot from a disk on the machine that has the card you're trying to flash, that would be good, since you can't PXE boot in theory.
 +Hopefully you're using some Linux and you have syslinux and grub2 installed.
 +Add memdisk:
 +  sudo cp /​usr/​share/​syslinux/​memdisk /boot/
 +Add the dos diskimage you're going to be flashing from:
 +  sudo mkdir /​boot/​images
 +  sudo cp dos.img /​boot/​images
 +Update grub:
 +  sudo grub-update
 +Now you can theoretically reboot using memdisk to boot into DOS to flash the 3c90 rom that you couldn'​t pxeboot from before

 +gpxe undionly driver v1.0.1 hangs when "​initialising devices..."​ (although the chipset declares Intel UNDI v2.1 capability upon boot).
 +==== How to Fix =====
 +  * Buy another NIC. Really. I tried two and both did never work reliably (link problems -- either no link detected or DHCP answers missed -- could be a firmware issue, but how do I fix the firmware when I need to boot with that NIC??).
 +  * The undionly solution seems to be broken with that chipset. Use r8169 driver instead.
