Secondly, I tried a different ROM chip. I have just come to understand that there are 5 different generation chips which constitute the Rev A Rom. See:

My minitower had a 4th generation Rev. A chip. My old parts desktop machine had one of the earlier chips, although I'm not sure which one. In any event I switched out the ROM chips and my machine now boots just fine from the DiskWarrior CD. I'm thinking that it must have been the ROM chip, because I later reinstalled the RAM and it still boots fine. So now I have a machine that will boot in X, 9 and on a system disk. There is one thing though that is different: Now when my machine boots, the screen does not come on until it is past the the gray boot screen, with the little gear at the bottom, and comes on midway through the blue screen. I don't have any explanation for that. I really figured it would come on later since I'm booting off a Rage 128 card, but it was booting earlier before I swapped out the ROM chip. Go figure.
So at least for now the problem is fixed. I believe that either the 4th generation Rev. A ROM chip doesn't play well with OSX 10.2 or my particular ROM chip was corrupted. Anybody have any thoughts? Sorry for the long posts, but I hope no one else has to go through this.

I'm still having problems with my Beige g3 that I upgraded to Jaguar. I was going to run DiskWarrior, but it won't boot off the CD. So then I tried to launch the Jaguar system CD (which I had installed from just a few days before), and it won't boot. It displays the same behavior on both CDs It starts to launch and the grey screen with the apple in the center comes up and then 15-20 seconds later, it hangs. I can't figure it out. I've removed all cards, reset PRAM, reset CUDA, swapped out the CDROM drive, swapped out the PRAM battery. Same symptoms every time. Interestingly, it will boot the OS9system CD and the old Mac OS X 10.0 CD. It also goes back and forth between 9 and 10.2.8 on separate partitions just fine. The only anomaly I see is that sometimes a CD won't appear on my desktop in 9, until I restart on the 9 system CD. Also, when I removed the ATI Rage 128 card and went to the onboard video, it wouldn't boot at all off the CD, but it would off the hard drive in both 9 and X 10.2.8. This is really weird. I posted about this the other day, but I didn't get any comments, but obviously I've done a little more troubleshooting. Any thoughts?
