Why does this problem only come up in the system that has ISA Cyclades and
a tulip card?  The motherboard is a Tyan Tomcat I (with the old BIOS they
once produced that has NCR SCSI support).  I've not noticed this problem
in any of the other Tomcats I have using the same BIOS, same tulip cards,
but no cyclades cards.

This seems to be a potentially big problem, since if I have to shut things
down before rebooting to get the next boot to succeed, then adding a
hardware watchdog card (something I've wanted to do for some time for the
periodic lockups every few months) won't do much good.  Is there a chance
there's some BIOS setting I can change to deal with this?
