Hi, New to the list and to G4's. I just got a G4 from ebay, and like it alot. It only had mac os 9.1 on it so I installed os 10.2 (with the option of erasing entire hard drive). The computer has a scsi 17gb hard drive in it. I decided to buy os 10.4, and I should be getting it on Tuesday. Here's my problem, I was tinkering around with yellow dog 3.1 and installed it on the computer, it went well, and worked. Now I want to install several partitions, one with mac 9.2 and the other for 10.4. I installed my 9.1 cd, and it will not boot from it. I then installed my 10.2 cd and it doesn't see the hard drive. I went into the firmware and did a nvram-reset, set-default, reset-all and the computer rebooted but when installing 10.2 it still does not see the hard drive. If I try to boot with the 9.1 cd it comes up with a disk and a flashing "?". Any help would be greatly appreciated it getting this thing up and running again. Thanks, Bob
