I am new to Linux (no experience). I took a iMac G3, and tried to install Mandrake Linux PPC on it. The installation seemed to go fine except for a message referring to a missing "Apple Boot Strap Partition". Since I did not intend to double boot nor do I intend to put Mac software on the machine, I ignored the message. After the apparently successful Linux install, I rebooted and expected to see a Linux login prompt. Instead I get a flashing folder that alterantes between a smiling face and a big "?" in the middle of it. Nothing I did took me to a Linux signon.
I finally rebooted holding down multiple keys at the same time (I don't have the sheet in front of me but I think it was SHIFT-COMMAND-F-O)....and I went to a Linux text prompt. At the prompt I could move around in Liinux....but not knowing what exactly to do, I didn't accomplish anything. SUMMARY:
1. During the install of Linux, I used the Mandrake disk format utility, which erased everything Mac and loaded Linux partitions.
2. This utility completed successfully.
3. The installation step related to the "Boot Strap" gave me several nasty messages but also completed.
4. The remainder of the installation (GNOME, KDE, etc. all ran without me touching a key. No problems.
I'm told (by well meaning stander's by) that "yaboot" is somehow lost and that's my problem. I have no idea what to do next.
