If you're getting those messages, the system is running fsck for you, so
it's certainly present.  I think you would only get those messages about
the root filesystem after a question like "Root filesystem is dirty, OK
to check it?".  One thing you can do is: say no.  Then go to single-user
mode and run:

  fsck -o full /dev/root

and see how it goes.

Using the boot floppy, you would need to do this:

  mount /dev/hd0root /mnt
  chroot /mnt /bin/sh
  fsck -o full /dev/root

But I think this won't work because of the way root is mounted.  fsck is
only willing to check a mounted filesystem if it's the root filesystem
(according to the booted kernel).  When booted from a floppy, the floppy
is the root.  You _might_ be able to:

  mount -r /dev/hd0root /mnt
  chroot /mnt /bin/sh
  fsck -o full /dev/root

Doing it from single-user mode is probably much easier.

If you're still stuck, post the full messages you're getting during the
failed bootup.

I am booting SCO 5.0.5 from the Boot Disk, but it automatically runs the installation... I don't want to install, I want to boot to a shell so I can run fsck... how do I do this? I am pressing Enter at the boot: prompt, but there is never an opportunity to login as root, it just says Press <Enter> to being installation. Thanks in adavance.

See the "How do I crash out of the install script?" at http://aplawrence.com/Unixart/lost_root_password.html#install_script

I don't remember which part of that applies to 5.0.5; you'll need to experiment.

Thanks, per that article I could enter "tools" at the boot: prompt but it still continued with the installation script. I could not break out nor did I see any menu giving options to go to a shell.

That's what it is supposed to do -did you read the link that points to http://aplawrence.com/BDD/507cd.html ?

Thanks, yes I did read that article but it indicates a menu appears... this menu never appears for me. The difference I see is that I am booting from a 5.0.5 boot disk and not the 5.0.7 CD. Could that be the difference? I don't have a 5.0.7 CD...

I don't remember 5.0.5, sorry. Try one of the other methods.
