That's what I've read during my Googling.  What worries me is if grub didn't
detect the drives during the reboot phase of the installation, I'm hoping it
does the right thing when Knoppix is running.

Cool.  I like this much better than swapping out grounding pins or IDE
cables.  I'll give this a try first.  Don't go into work until Thursday, but
I'll give a status report when something new develops.

Also, I'll try downloading a new version of the Sarge Beta installer.  I'm
sure a new one was released since I downloaded my current copy.

Thanks!
Pete
