sys/arch/hp300/hp300/autoconf.c: revision 1.113
Fix a 20 years old botch by me in setbootdev() on switching to MI SCSI.
setbootdev() updates bootdev data shared between BOOTROM and
it notifies BOOTROM to choose a current root device as a boot device
on the next boot, but I didn't understand the intention and then
it has been broken on SCSI disks. Sigh.
(I wonder if no one has noticed this old feature for 20 years..)
