I'm tearing my hair out on this one; anyone here know a lot about Linux on Macs? I posted the following message to the Yellow Dog email list and got no response. Perhaps one of you is a closet Mac expert? :) <-------> I've got an original iMac and I want to run YDL (www.yellowdog.com) on it, alongside MacOS. I originally wanted to tri-boot 9,O OX and YDL, but I've given that up since involving OSX was too complicated (and didn't run fast enough on the 233 iMac anyway). Now all I want to do is run both OS9 and YDL. I've followed the install instructions carefully. Twice. Both times (with a HDD format in between), the machine hung upon trying to load yaboot. I installed OS9 first, then YDL. I'm currently using the machine in question, in OS9... I get it to boot by zapping the PRAM. It's the only way to get it to startup. Does there exist a clear set of instructions on how to install YDL and OS9 on the original iMac? I've been unable to find it (and believe me, I've looked). Might there be, wonder of wonders, a way to run all three OS's on this machine? Could someone please help me?
