thanks for the info on the EISA bus.  I didn't recall the throuhgput of that
channel.

speaking nostalgia, I had an old 486 mb with ISA/EISA that board was
awesome.  I used it for a while as a desktop (hand me down style) and worked
flawlessly.  The best part was that I went from that old 486 to a p2/266.
skipped the complete pentium/ppro series.  although having a ppro would have
been nice.

ahh.. memory lane :)

EISA is a 32-bit bus with a maximum throughput of 33MB/s.  That's plenty
for 100Mbit.

I have a pair of 3Com EISA 579's that are 100Mbit.  They worked fine in my
IBM PC Server 320's for years, and they were capable of transferring
100Mbit of data on Pentium 133's running OS/2.  Ah, the days...

There were a *lot* of 486 PCI motherboards and only a *very* few that were
486 PCI and EISA.  Servers, yes.  Average motherboards, no.  You should be
able to look at the slot and tell if it's EISA.  It'll be taller than an
ISA slot (by about 1/4 an inch or so), and you should see the second row
of copper fingers below the top one.  Odds are, it does *not* support
EISA.
