- If you are able to login as another user run /etc/hwconfig -hc and look for the root controller hardware adapter driver of the disk for the root disk.
For example:disk – – – type=S ha=0 id=1 lun=0 bus=0 ht=ciss unit=1
Sdsk – – – cyls=8717 hds=255 secs=32 unit=1 fts=stdb
In this case the ht=ciss shows it is the ciss driver.
- Download from ftp.sco.com or from the 5.0.7 installation CD in the /images/boot directory get the btld for the root controller and create a btld onto a floppy or CD rom.For floppy:format /dev/rfd0135ds18dd if=btld.img of=/dev/fd0
- Insert the 5.0.7 installation CD and reboot the server. (You may have to power off and on, since you cannot shutdown).
- At the boot: prompt load the btld (If needed)For example:Boot: defbootstr link=”ciss”

- Now change the root system to the hard drive./mnt/opt/K/SCO/Unix/5.0.7Hw/etc/chroot /mnt /opt/K/SCO/Unix/5.0.7Hw/bin/shYou will then have a promt with the #
