I've worked with 3c905C-txm cards. I actually replaced
a bunch of 3c905b cards with the 3c905c-txm.
First of all, are you SURE your 3c905b cards have the
appropriate ROM to support PXE. If there is nothing
plugged into a large socket at the back of the card, I
think you may be out of luck unless you buy a ROM chip
to go in the socket.
I found it was less expensive to buy 3c905c-txm cards
in bulk off eBay than to mess with buying ROMs to plug
in my 3c905b cards. The 3c905c-txm cards are
netbootable with the stock ROM chip.
Also, I had to use 3Com's MBA flash utility and card
configuration utility to flash my 3c905c-txm cards to
the most recent MBA firmware, then use the config tool
to turn on netboot. There may be a similar utility for
the 3c905b cards....dunno.
Once you've got a card that's netbootable, you'll need
to make sure your DHCP server is sending the right
information to the client when it queries it...Check
your DHCP logs to monitor your progress...When you
make changes to DHCP zap /var/lib/dchp/dhcpd.leases
and restart dhcpd...In case it helps, here's the
relavent entries in my dhcpd.conf ...Keep in mind that
I use a different server for DHCP than my LTS...Once
you get DHCP working, start watching your TFTP server
logs for activity.
Best of luck...make absolutely sure your cards are
cabable of PXE before getting frustrated with DHCP,
TFTP etc.
