Uh... that's what the Boca boards are. They're probably the most widely
supported multiport boards among free Unixes, which is why I got one when it
popped up on Ebay. It may be that this is just a bum unit, or more likely
there's a conflict. The I/O space it requires is huge (it's set up for
100-17F right now), and I suspect there's something else lurking in there,
although I don't know what. I don't think anything is using IRQ 5, since I
had an Ethernet card on that for a while, but I can try fiddling that, too.
The purpose of the exercise is to have a box that I can telnet to from
my main machine, as I did with the Lantronix, so I can have all the
consoles in a flock of xterms on the second head.
