I have experienced this problem several times in the last few months,
and it *always* occurred after I've mucked around with the SCSI devices
I've attached to the IIx and so I've concluded that it's a "Your SCSI
setup is messed up" announcement. And it goes away after I've fixed the
SCSI up right.

But you say your only SCSI device is just the internal 80meg? Or are
there any other things you left out?

If it's just the internal, is there a possibility the internal SCSI
terminator's kablooey? (I don't know -- I'm not a hardware guy.)
