I was frustrated trying to get a built-in 3c509 isa nic to net boot on a Dell
GXM133 workstation. The solution was:
1. Download 3Com's DOS nic utility
2. Use it to disable isa plug-n-play on the card and assign an irq and port to
the nic
3. Set option-128, option-129 in the workstation setup in dhcpd.conf file
4. Restart dhcpd
I wish I could remember where I found the following instructions -- I would
give credit. Perhaps it was older ltsp docs.

What if you still get a tftp error 1 - file not found?
Make sure your mac address above is correct. dhcpd will assign an ip
address to
the workstation. If the mac is incorrect, the ip address will not
correspond to
the ws setup in dhcpd.conf and you'll get tftp error 1.
And if that doesn't help?
