I have installed OS 10.1 on a 7500/225mhz-604e with 112mb. It took forever to get the correct combination of SCSI termination and RAM to get it to take, and the install process was many hours on my small HDs. It seems to run pretty quick, at least as quick as on my 366mhz G3 ibook, so I'm happy enough. The problem is that I installed using the onboard video, with only 2mb VRAM installed (I had 4mb, but a 1mb VRAM stick had some bad pixels, so I had removed a pair). I got a new 1mb, and when I installed it, it scrambled my monitor (old 20" SuperMac) during startup. The smiling face is OK, but then when the blue OS X comes, it scrambles. I rebooted in OS 9.1 and it was fine. I switched resolutions etc, and the VRAM was fine, everything great in OS 9.1. I tried rebooting in OS 10.1, and still scrambled. If I remove the new VRAM, it boots fine in 10.1. I dread a reinstall. I think the long 'system optimization' process is what locked me in to the 2 mb VRAM configuration. Is there a way I can add this extra 2 mb VRAM without a system reinstall? I've already zapped my PRAM. I guess I could pull the battery and push the button to see if clearing the NVRAM helps, but I thought I ask for some help first. Perhaps there is something in XPostFacto that might help here? Suggestions? Thanks! Kris Tilford
