Hello, I have installed 10.2.6 on my 9500 upgraded to G4, but I can't "clean" switch between OSX and 9. The processor upgrade card is a nice xlr8 MAChCarrier SSE/MPe with a G4 at 500MHz. The soft/drivers I use is xlr8's at the 9 side, and PowerLogic's at the X side (the last xlr8's X version I purchased from them won't work here at all ???)

I use XPostFacto to boot X, with no problem at all. But when I try to boot back to 9 (not Classic), my computer wont boot at all (black screen), so I have to zap pram a couple of times and insert xlr8's firmware emergency floppy and then it boots in 9.

Any help, please?

Thank you.

Don't quote me on this - but i have a sneaking
suspiscion that a computer can be upgraded only
so far - and the Powermac 9500 only has the logic
board bios (regardless of processor) - to take at
maximum - Mac OS 9.1.

It's obvious that you "can" get it to kind of work the
way you're doing it - but as for a seamless
solution - it may simply not be able to cut the
mustard on the swapping scenario you've
attempted - as it's architecture is out of date
(according to Apple).

I could of course be wrong.

Try partitioning the drive 30/70 - 70 for Mac OS X -
and run Mac OS 9.1 for starters on the 30/
Partition.

Experiment.

tell us how you went =)

cheers

clockwork, thanks.

I have two disks, one for 9 and one for X.
Well, the OSX software from daystar is supossed to work but it doesn't in my computer so I don't know what to think about, maybe I'm doing something wrong I don't know for sure.

I can boot with no problem at all in to X, but I can't get back to 9 without zapping pram first... I will investigate for sure, I have to :)

It was a card problem as I was told by the xlr8's tech support staff. They sent me a new card!! and now everything's fine except a ram problem that doesn't let me use their cache enabler in X, it works fine in 9: the dimms pass all tests but I was told that it would more than probably be a ram problem, so I would like to ask where is a good place to buy ram for G4 upgraded pci Macs and if there is anything to be taken in to account when choosing ram for these upgraded machines.

Thank you,
