Hello all !
A friend of mine with no net access has recently bought 1.5 for his
386 with an ESDI disk. After preparing a partition with MINIX fdisk
for MINIX he installed that partition as the root device. The first
four partitions are organized as follow:

Partition:   1       2       3         4
         | MSDOS | MSDOS | MINIX | SCO UNIX 3.2.1

He uses the UNIX boot program as the default. Some days ago he tried
to boot MINIX from the boot-disk. To change the root device he uses
the "r" option but he made a mistake, he selected the wrong partition
as the MINIX root-device. MINIX stops with the "invalid root file
system .." _but_ also crashed the UNIX boot program. Rebooting let
him access MINIX but not UNIX or MSDOS. He verified this behaviour
by reinstalling UNIX and doing the same mistake (I think he selects
partition 4) again.

His question is: Why does MINIX crash the UNIX boot-program/boot-block ?
