'Souped up' beige G3 DT (400 MHz ZIF, 768MB RAM, 80GB WD 7200 RPM & 40GB IBM 5400 RPM HDs), previously running OS 9.2.2 and 10.1.5, each installed in its own 8GB partition, those two partitions being the first 8GBs of the two HDs.
When I initially ran the Jag installer, it refused to recognize ANY of the existing partitions as 'legal' - saying that NONE of them were w/in the first 8GB (even though the 10.1.5 installer had no prob w/ the partitions the way they were!), so I copied about 20GB of data from the IBM to the WD and reformatted / repartitioned the IBM with a 7.45GB partition w/in the first 8GB. THEN, the Jag installer considered that volume 'kosher', but the install failed w/o any info about why.
My next attempt was to d/l and use Ryan Rempel's XPostFacto, but that, too, failed with a screenful of UNIX gobbledeygook.
Throughout this whole adventure, 9.2.2 has continued to boot and work like a charm (God, I LOVE Macs!) so I've always been just a restart away from my 'usual' functionality - which has made ALL the difference because I have not been able to 'plug away' at this prob in any kind of concentrated way, only attack it a little here and there as the week has progressed.
And finally, brought to you by the Third Time's the Charm Department, I reinstalled 10.1 on my freshly formatted, definitely-smaller-than-8GB partition, ran the Jag installer to upgrade that (w/o a glitch), then d/l'd and installed the 10.2.6 Combo Updater (also smooth as silk!).
So I'm a very Happy Mac Camper this weekend!
But I'm warning y'all - now that I'm using the Big Cat, I'm running into Some Questions ... and you know what happens when I can't figure out something about my Mac, dontcha?
****I post a thread here at Tee Ess!****
As a fatter of mact, I'm gonna go do that right now....
TIA, to all those who've helped w/ my past probs (and future ones too)!
