I have a Quadra 950 that I recently installed A/UX 3.01 on. Everything worked fine, booted into A/UX, no problem. I had split the HD into 3 partitions (1 for the MacOS that comes with A/UX, 1 for A/UX and 1 for OS 7.6.1) so I proceded to install 7.6.1 onto the third partition (I actually can't remember the order of the 3 partitions, it that matters). That went fine, boots into that no problem.
But, now it doesn't want to boot into the other partion again. Running Startup Disk and selecting the A/UX-MacOS volume seems to work except that if I run it again, both volumes are selected (I can select either one of them again, but both are always selected when I run it again).
So I thought there was some problem with the PRAM so I checked the battery (it is almost new) and it gave 3.64V. I zapped the PRAM several times, same results.
Then I thought, what if I make the 7.6.1 volume unbootable? I changed the name of the System file which "decertified" the system folder (or whatever that is called). Rebooted, and it still wants to boot into that volume, except that now it comes up with error 41 in the boot process. Trying to reboot from a CD by holding down "C" (or does that only work on PowerMacs?) has no effect.
I have yet to try to boot from a floppy, but what the he** is going on? Is the PRAM fried? Is there a CUDA switch somewhere on the motherboard? (or is that just on PowerMacs?).
Any help would be appreciated.
