Still have the Adaptec SCSI card out
AND nothing other than the bare essentials connected?
Might try zapping the PRAM / rebuilding the desktop… etc. and then try-try again.
Something’s definitely hokey.
The “simples”…
• Fresh or definitely good-tested battery?
• All internal dust removed?
• No frayed or damaged mouse cord / connections?
*All the above rather moot if Panther works without fail.
HD partitioned into two partitions from the Emergency disk - one for Panther
and one for OS 9? Installing OS 9 first until stable / successful - AND THEN
installing Panther on the second partition.
If you can’t get this done, I’ve an AGP here that I might go through a similar
installation on to see if there’s some “little thing” I’m missing (or have forgotten)
in this type of install. Could be as simple as some extension or video driver that
needs excluding / removal. (It’s been awhile, here.) Check all of the above
“simples” and then will consider possible Conflicts.
Try booting with all extensions off. (Cold Boot, holding down the shift key.) If it
boots and mouse / menu functions then work without a freeze…
then your detective work truly begins.
*Likely a simple matter of turning off some extension(s).
