How to reinstall SCO unix, and restore from SCSI tape drive?
If you have full system backup, you don’t need to install SCO to a new HD, all you need to do is to use the SCO emergency boot FDs (Boot & Rood FD, can make from a working SCO box), use the FDs to boot up to single user mode, run divvy to partion the HD as the same layout as your old one (the size for a partion can be bigger than the original one, you need make sure it is bigger enough to hold the data in the partion), then mount the partion one by one and restore from backup. Please have a look at your backup script, to find out the backup format. It is likely use “cpio”, not tar, since the SCO version of tar can not handle the specify files.
