do you know where I could get more information on this?  are the
header/checksum/other format details different?  do you know where I could
get a package to make pci eproms or the information I would need to modify
netboot to make them? 

I am currently testing on a DELL Optiplex XMT 5100 (in case that means
anything to anyone), but more importantly, the CMOS setup doesn't have any
options for configuring my two pci slots.  is it possible the bios on my
test machine is just too old and I should try to test on a newer machine?

I got the packet driver for the 3c905 (from the 3com ftp site), and used
it to make a boot image with netboot.  I have successfully used the
resulting floppy image (cat image.flo > /dev/fd0) which is generated for
test purposes, but I have not been able to get it to execute from an
eprom.

thoughts?
