The problem is the motherboard's BIOS. Some motherboards support
soft-reboot and some
don't. I had this problem running an AMD486/100 with an early AWARD
bios. Got a new motherboard running a later revision of AWARD bios, and
it went away. Later changed to yet another motherboard running AMI
bios, and the problem didn't come back. Now I test
every motherboard I get, and if it doesn't reboot correctly, I send it
back.
