     I believe so.

     Here's the catch.  The ISA bus tops out at about 4 MBps, or about
40 Mbps.  In other words, you can add a card that can do 100 Mbps on
the wire, but it won't be doing anywhere near that on the ISA.  Also,
since it only has an ISA bus, you're disk(s) will be PIO only (i.e.
slow -- topping out at 4 MBps).  Don't forget, that only one thing can
use the bus at a time, which means that the effective file serving rate
will top out at 20 Mbps.  In other words, it doesn't matter what you
do, this thing is not going to be able to serve data fast enough to
keep a bunch of newer machines happy.  Dump it and use a real machine.
File servers require machines with lots of I/O power, and the ISA bus
just doesn't cut it.
