My problem turned out to be caused by a disk which has OS 10.2.2 on it apparently that disk wanted to take over and dominate my poor little S900 giving me the same video problems you spoke of. The cure------ I think Jeff is right about the NVram but after switching video cards and alot of other stuff I got my computer back by doing the 30 sec cuda press, zapping the param about 10 times and disconnecting the drive with OS 10.2.2. Once the machine started upfrom another drive in OS 9.1 , I got it restarted with the with the 10.2.2 drive connected by holding down the option key which forced the OS 10 drive to be ignored till the machine had running video in OS 9.1. I then started OS 10 from XPF restarted again in 9.1 with the option key and everything was back to normal. If this seems wierd--- OK ------ I've been troubleshooting electronic equipment since 78 and alot of times I think a good undergraduate course in voodoo would be more useful than a computer manual to get things back to normal. The main point is that I tried three video cards which were all good before I achieved stasis. I seem to recall another harddrive corruption creating the same sort of havoc before I ever tried OS 10. In that situation I had to remove the drive set the startup disk cp to use a good drive and then reinstall the bad drive and everything worked. Maybe something in that startup control panel gets corrupted --- it obviously loads quite early. MT -- SuperMacs is sponsored by <http://lowendmac.com/> and...
