Indeed.
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.
Hmm... interesting. New ones on me.
I've also seen someone put a 100Mbps PCMCIA card
in an ISA-PCMCIA bridge,
but that's stretching the definition a bit.
*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.
