I/we don't get anything about "isa table corrupt".  It just forgets
things sometimes.

Not every time.  Sometimes it hangs instead of going back to the ">>>" 
prompt when I "halt" NetBSD. Oddly, it seems when it hangs it's *less* 
likely to forget it's settings than if it returns to the SRM prompt
before the box is powered off.

There's also other strange stuff going on with the vga scrolling; SRM
sometimes looks like it's stuck in a vt100 scrolling region somewhere
in the middle of the screen.

Will try this trick; thanks.
