This article is from a FAQ concerning SCO operating systems. While some of the information may be applicable to any OS, or any Unix or Linux OS, it may be specific to SCO Xenix, Open Desktop or Openserver.

There is lots of Linux, Mac OS X and general Unix info elsewhere on this site: Search this site is the best way to find anything.

Installation FAQ

How do I crash out of the install script?

On OpenServer Release 5, boot from the boot diskette, and at the Boot: prompt, type

tools

This is not an undocumented option to the boot command, but rather a special line in /etc/default/boot on the installation diskette - so you can't use it from anywhere but your installation boot diskette.

And you can't use it anymore at all. Tom Melvin pointed out:

The 'tools' option broke around 5.0.4 time - I know it does not work in 5.0.5 or 5.0.6 Don't have a 5.0.4 box around to test it with.

Tom's right: I booted "tools" on a 5.0.6 install disk. Part of the functionality of "tools" is still there (and in fact "tools" still is a boot option). If you press F8, you get the same screen that "tools" gave you directly, and you can do a shell escape. Unfortunately, so far I haven't been able to see how you can mount the existing hard drive. The old "hd0root" device is not there, and attempting "mount /dev/hd0a /mnt" didn't work.

A SCO TA says that you can still do this, though; See: http://aplawrence.com/cgi-bin/ta.pl?105312

Mike Pope commented:

What I did was to break out to the shell, run divvy and give the filesystems
names.  At that point a device node was created and I was able to proceed.
I think this is covered elsewhere on your site using mknod, but it ought to
be here as well - just a suggestion.  The Caldera TA also misses the
creation of /dev/hd0root.

For older SCO Unix/Xenix/ODT releases, wait until the question early in the process that asks you what your keyboard type is. For character-mode installations, this is a regular textual prompt; for ODT, it's a box in a curses-style installation program. How to break out at this point depends on the OS. Under Xenix, press Del. Under Unix, type shell and press enter. Under ODT, press Control-A.

How can I generate and save a debug logfile for an SCO OpenServer 5 installation or upgrade (not strictly related but worth reading :-)
