I just recently received a PowerMac G4 (my first mac) that I decided I wanted to upgrade. I honestly know nothing about mac, but wanted to try something new, maybe get away from windows for a while (Except my notebook). Anyway, I tried installing my 200gb maxtor from my PC (formatted with NTFS with both windows xp and a vista BETA installed to dual boot), had the jumper set to slave, tried to boot, and I got what someone in another forum referred to as "The NoBootX" (crossed out circle). Someone in the same forum said to try setting it to cable select, I tried, but I got the same problem. I tried setting it to slave and using the MacOSX cd to try to use the disk utility, but when I pressed C, it gave me a screen saying I needed to restart, as well as some black bars/white text saying something about a kernel panic. If anyone can help, please let me know,I'd really like to figure this out and get my drive working. Heh, the one in here I think is a forty gig , and it's close to finished.
