I did find an alternative method of booting from a CD with CD driver conflicts when one can't access the Start Up control panel to change the HD, and short of having to open the computer and disconnect the power to the HD having the corrupt OS. A bootable CD will boot with a restart in spite of driver conflicts when holding down Command-Option-Shift-C, after which one can select an alternative start up HD.
Thanks again, Bernie Thanks Paul, I had done exactly as you suggested to establish the back up drive (#2) as the start up drive and get the computer up and running. I verified the HD (#1) containing the Corrupted OS 9.1 using HDT's Disk First Aid which showed no problem with the drive. So, apparently the corruption is in the OS on that drive. I could copy the contents of #1 HD to the currently unused #3 as a current back up of the good data on #1, before playing with its corrupted OS. Can I just overwrite, or delete and replace the full OS easily on that drive?
