Hi, I have an old PowerPC 266MHz beige tower. I just replaced the original SCSI hard drive with a Maxtor 40GB IDE drive. The maxtor drive came from an old Windows PC. Here's what I want to do - Boot from Linux CD (edubuntu 6.XX for Mac) and install it to the Maxtor HDD. I'm assuming that in the process of installing Linux, it will reformat the Maxtor. So I don't intend to run Mac OS on this, but rather Edubuntu. The Edubuntu CD was downloaded on a PC, and the ISO file was burned in the same fashion as other variants of Ubuntu that have worked successfully on other PC's. Now here's what's happening with my PowerPC. I can't get it to boot from the CD drive. I tried holding down "C", and later I tried "D" when powering up the tower. I never get the CD to boot, but instead I get a grey screen with the mouse in the upper left corner, and a Floppy Disc icon in the center of the screen with a question mark on it. Nothing else happens. I'm stuck at this point. Please go easy on me if I've overlooked some basic Mac conventions. I'm brand new to Mac. I'm guessing that the grey screen and Mac-looking icons are coming from something in system ROM since there is no Mac-formatted drive in the tower. Can anyone offer help? Thanks!
