looking for eprom info re 3c905b

[Andru Luvisi]

I'm sorry if this is an inappropriate place to ask this, but this is the
closest I've been able to find and I'm hoping someone on this list will
have some knowledge related to my problem.

I work for a university library, and after evaluating 6 proprietary
network computer type offerings, we decided we could do better on our own.
our current plan is to use netboot (http://www.han.de/~gero/netboot.html)
to boot linux with a read-only nfs root partition.  we have it almost
fully implimented (fully implimented if we use an NE2000 or 3c509 ethernet
card), but we can't figure out how to get a boot prom to run in the 3c905
(which is what we'd greatly prefer to use in case our campus goes over to
100BaseT within the next several years). 3c90xcfg shows the eprom as
mapped into a region near the top of the current ram, rather than anywhere
in 0xc0000-0xef800.  it's not that the eprom doesn't work... it's never
executed!  3com tech support has been anything but helpful, and I'm
begining to run out of ideas to try.  I would be greatful for *any*
pointers to technical information on booting from an eprom using 3c90x
cards, or *any* advice anyone can offer. 

thanks,
