How to get very old 3c905b with iPXE to work?

Hi NiKiZe,
thank you for your reply.

And when you have done that and confirmed it working you could start experimenting with rom burning.

OK, then we do it in these two steps.

What I want do to is to use the NIC to Boot the Box as a LTSP client. The filename is handed out by DHCP, the the kernel by TFTP.

So I did "Generating iPXE build image version 9720f" as "Standard build" on as ".ISO bootable image", which then in turn is stored on an USB-Stick using dd. The embedded script was specified as follows, based on the web-examples:


dhcp && isset ${filename} || goto retry_dhcp
echo Booting from ${filename}
chain ${filename}

... this boots me nicely into my LTSP environment. - Good Cool

However, the only changes from my previous failed ROM Attempt were:
  • Advanced Build
  • ROM binary (10b79055.rom)
  • PCI-Vendor & Device ID 10b7:9055 (according to lspci)
  • burning the binary using zprommer to an MX28F1000 EEPROM
  • fitting the 3com NIC with the EEPROM

...well I'm also not sure what to do or try Huh.

Since the script is working as expected and there are no other config options on rom-o-matic besides the GIT revision, I see little hope to make this fly as planned.

For the time beeing I rule out the burned EEPROM Chip as source of failure, since it verifys "OK" and it is recognized by the NIC, since it shows an iPXE message upon startup.

Any further ideas?

Thank a lot
