Operating Systems SCO Error message during boot Post 303004908 by hicksd8 on Tuesday 10th of October 2017 03:39:26 PM

I also (think I) remember that, when booting from CD/DVD or floppy, the kernel creates a device node 'hd0root' to point to any hard disk root filesystem. Therefore to take a look around from CD booted maintenance mode you can:

Code:
 
 # mount /dev/hd0root /mnt
 # cd /mnt
 # ls

Obviously to umount that you would:

Code:
 
 # cd /
 # umount /dev/hd0root  (or # umount /mnt)

Without hd0root mounted (of course) you can:

Code:
# fsck -n /dev/hd0root

to see any damage to the hd root filesystem.

Hope that helps.
