LOL with tears in my eyes. Well, I thought I would trick the G4. I put the original ATI Rage Pro 128 (OEM) in another slot and connected my monitor to it instead so the display would be legible. My reasoning was that then I could boot to my Panther drive and install 10.3.3 which theoretically installs the correct driver for the ATI Xclaim 3D Plus. Now I have totally lost the Panther drive!!!! Yuck!! I have used DiskWarrior, TechTool Pro 3, Norton 6, SCSIProbe 5.2 and Disk Firstaid from the OS9 install disk. None of them can even SEE the disk! Its as if I had disconnected the cable to the drive, which I'm going to check right now. (I don't see how I could have accidentally done that but you never know until you check.) Do any of you know what mysteries are at work here?? xxxxxxxxxxxxxx >[...] Panther worked fine on the ATI Rage Pro 128 (OEM).

I see only two solutions. First, take your Panther drive to another Mac and do the upgrade there. Or, two, ask a friend with the correct version of Panther to e-mail you the ATI Rage Pro kexts (they should be in /System/Library/Extensions/), which you could copy to your Panther. I'm not sure how well this will work, but it's worth a try. _________________________________________________________________ FREE pop-up blocking with the new MSN Toolbar get it now! http://toolbar.msn.com/go/onm00200415ave/direct/01/
