I recently got ahold of a B&W G3, which I *think* has a processer upgrade, but I'm not sure (I'm primarly a linux/pc guy, but I'm never one to turn down a box that could be decent a UT2K4 server). I installed OSX 10.3 on it, with little insident, however after the first boot of it, it started having problems. First it told me I needed to reboot when I booted up, but I was able to get it to boot by holding shift on boot-up. Figuring maybe something wasn't updated, I ran the software update program, which downloaded over 100megs of updates (including one rather hefty OSX update). After it finished downloading/installing them, it "optimized" the hard drive for me, and then asked me to reboot. Not being one to cause problems, I rebooted. However, it once again wants me to reboot on boot up (doesn't even finish loading the os, just waits 15 secs then says "You need to restart your computer. Hold down the Power button for several seconds or press the Restart button"). Only the reboot button does anything at this point, even holding the power botton leaves it stuck. I have tried holding shift on boot-up, but it just locks up in the loading part. Also tried the Command+Option+P+R then wait for 4 chimes. Nothing seems to do the trick. Anyone have any ideas how I can turn this system into something beyond a footrest? Edit - Shortly after posting this, it was willing to boot after another Command+Option+P+R x 4, then shift+boot, but that still leaves me in safe mode and it seems unreliable at best. Please advise!
