I quit trying to run without db.  Last night I tried to debug 386 Minix
for a few hours and only decided that the general protection exception
was happening after the TTY proc was initialized but before MM was
initialized.  I didn't have time to track it down farther.

This morning, though, I rebuilt everything after changing the number
of buffers in the cache to 30, and 386 Minix started without any complaints.
I'd like to find the source of the trouble when using large numbers
of buffers and the plain Minix bootstrap.

I guess I'll have to figure out how to use shoelace to boot Minix
so I can have lots of cache until I get this problem figured out.

Thanks to everyone who responded!
