I just bought this all in one at an auction and am presently upgrading it for creating/editting music (garageband, etc.). Put in a new Seagate 80gb drive (as master), more ram, and 9.1. I have a problem getting the CD rom drive to show up in the profiler sometimes (problem 1). I moved the jumper around and it finally showed up. Then I tried to load OS 10.3 which locked up before it even began to load (problem 2). Then upon restart into 9.1 the CD didn't show up again. I also would like to know which USB/Firewire combo PCI card to go with. I also plan on upgrading the zif socket to a G4 500ish thing. Any thoughts??? Thanx

You canīt install osx 10.3 with a g3 that donīt have USB on the motherboard. Try osx 10.2

you should go to www.lowendmac.com and read about running osx on the beigeg3 withregarding of thepation size limit for the first 2gb (must be partioned 2 2gb size)

Here is more info from lowendmac.com Mac OS X If you have a hard drive over 8 GB in size, you must partition it. The partition containing OS X must be within the first 8 GB of space or you will not be able to run OS X. (If you are creating the partion within OS X, it must be 7.45 GB or smaller as reported by Disk Utility, because sometimes a GB is billion bytes and sometimes it's 1,073,741,824 bytes.) You can only boot OS X from a "master" drive in the beige G3. This applies to hard drives and CD-ROM drives. If the CD-ROM is set to slave, you will not be able to install OS X. If the hard drive is set to slave, you will not be able to boot from it. Non-Apple upgrades and peripherals (such as unsupported USB devices, replacement drives, and third-party memory) may cause problems when installing or booting into Mac OS X. Be sure to read and follow Apple's "Read Before You Install" instructions to increase the likelihood of getting OS X installed and running on the first try.

I can tell you how to do all above and get a copy of osx 10.2 cheap.Im ahktopus on hooya
