To zap the PRAM, hold down Command-Option-P-R after the startup chime.

However, you might want to do the following. Hold down Command-Option-O-F to go into Open Firmware. Once in there, type "reset-nvram" and hit return. Once returned to the prompt, typr "reset-all", hit Return, and the Mac will reboot. Be sure to leave out the quotes on both commands. Hope this helps.

Did you read this link posted later in the thread?
http://www.thexlab.com/faqs/kernelpanics.html

It explains very well what a kernel panic is, and how to resolve it. Specifically, the most common cause of kernel panics will be defective RAM. Try getting it tested with Remember, or test each DIMM module like the article suggested.

Run a Disk Utility check, and also use it to Repair Permissions.

And the last (but most drastic) thing you can do is reinstall Mac OS X (either Archive+Install will preserve your data, but will cause more HD bloat, whereas Erase+Install will not cause bloat, but will erase everything).

"kernel panic"

i was installing MacOSX 10.4 tiger,i had 10.3.9 panrther. When I insert Disk I was told to restart the
computer to begin the installation but the cd had Scratches so i had to stop in middle...n after i stared my laptop again i could only c the grey screen with apple loading icon, that y i taught doing this :

Hold down Command-Option-O-F to go into Open Firmware. Once in there, type "reset-nvram" and hit return. Once returned to the prompt, typr "reset-all", hit Return, and the Mac will reboot. Be sure to leave out the quotes on both commands.

Then after doing this i found the "kernel panic",,,,

so know can u help

so know can u help

Yes I can. Buy a new Tiger disk, because there's no way you'll be able to complete the installation with the state your current disk is at. And reinstallation of OS X is the only way to fix this problem.

Hope this helps
