What kind of EPROM chip do you use? Is it the same one that the
manufacturer of your network card recommends? Have you used DOS's
"debug" command to verify that the EPROM gets mapped into memory? Is
the network card configured to enable the EPROM. Is the system BIOS
configured to not put cache/shadow RAM into the same location that you
have the EPROM? Usually, it is possible to use a different size EPROM
than the hardware was designed for, but there are a couple of things
to watch out for; you might want to look up the pin schematics and
verify that the 28pin and 32pin chips are truely compatible (you might
have to build an adapter that provides power on a different pin).


I hope, these suggestions are somewhat helpful
