Strictly speaking, DOS is not limiting your signalling
speed,
but the ISA bus could be.
For 100Mbps ethernet, yes. You can only push a fraction of the bandwidth.
There was one, only one, 100Mbps ISA card I ever
ran across (by 3Com, but I can't remember the model number)
3c515
Might not be the only one, though. According to Dan Kegals Fast Ethernet
page (http://alumnus.caltech.edu/~dank/fe/) there's a rumor that Cogent and
Olicom had ISA 100TX cards. I've never seen or heard of one in the wild.
I distinctly recall there was a 100baseVG ISA card (I had a client who was
bad at math who wanted to go VG so they wouldn't have to upgrade to PCI
desktops). We all know how that turned out.
I've also seen someone put a 100Mbps PCMCIA card in an ISA-PCMCIA bridge,
but that's stretching the definition a bit.

Didn't Intel make ISA 10/100 cards? Or were they PCI only?

New subject: ISA nics (was: cctalk Digest, Vol 40, Issue 15)
Speaking of ISA NICs, I have a boatload if anyone needs some for cost
of shipping. ISA and PCI.

Hmm... interesting. New ones on me.

*slaps forehead* - I'd forgotten about that solution. I have a PS2/e
(IBM's "green" 486SLC box w/1 ISA slot) with the quad PCMCIA ISA card
(two PCMCIA slots out the front, two out the back). Mine is presently
loaded with RedHat 5.3 (it works w/16MB of RAM) and four network cards
for use as a software development "faux Cisco PIX" (multiple DMZs, but
not enforced security levels). At least two of the four NICs are
Xircom 10/100 cards. I think all of the 3Com 10/100 NICs are Cardbus,
but there are a few Linux-supported 10/100 16bit PCMCIA NICs (though
I'm not as certain about DOS and cardbus services, etc).
I've picked up single-slot PCMCIA ISA boards for around $25 at Dayton.
Dunno how easy they'd be to find now.
