I was able to restart windows and tiger several times, but when i just went into mac os it loads my startup items and then it goes to kernal panic. i thought that my firmware wasn't updated but i booted from the os dvd and went into the hardware config thingy from the Install portion. My firmware matched up to the one that my laptop had, but why would this happen then? I am sorry that there are typos and that this seems rushed, but i am freaking out because i wasn't even able to boot into the safemode without a kernal panic! Thanks!
