This problem is not something that can be patched in the BIOS. Here is what is
going on:
Normally, all goes well & I can boot the caching BIOS with typeahead
Sometimes, that BIOS won't boot. Everything else does: the
caching BIOS without typeahead, the non-caching BIOS with typeahead,
and the normal BIOS
I open the box, push in the USARTS on the I/O card, and all will be
well again (for a while). It will flake out the same way later.
I haven't found a solution (if somebody out there has one, let me know!), but
I haven't been looking to hard - I spend most of my time doing things where
I don't want caching (they do exist!), or I don't want typeahead.
This is the ONLY problem I've had with their stuff in over 2 years of work on
this machine, and casual use of about 30 others. The only other major problem
I've seen with Ithaca h'ware was a flakey power supply in a beta test site of
their z8000 system. They eventually flew somebody out to look at that.
