I posted this in the newbie forum, but I have gotten no replies, and it gets bumped down the page every time I check back, so I hope I might have better luck here.

So, I'm sitting here trying to install Fedora Core 6 onto my external hard drive via my MacBook, so I can keep using mac, but run Linux off the external any time I want, plus be able to hook it up to others computers and run it from there. 2 Problems. First, I downloaded the PPC edition of FC6 because I'm running a Mac, and burned a DVD image. However when I try to boot from the disk, it won't run! Which leads to problem number 2. What version of Fedora Core 6 should I download and burn to DVD to be able to boot into the new Macs with the Intel chip?
I really hope someone will be able to help. If you still don't understand what I'm attempting to convey:

I have a MacBook with the Intel Chip. I also have an external hard drive. I want to run Fedora Core 6 off my external HD while keeping Mac on my actual laptop. Any advice is gladly accepted. I really hope I can get this to work. Oh, also, I've never actually used Linux before, so I'm not sure how it works. If anyone could point me to a tutorial on customizing Linux or just learning how to properly use it, it would be much appreciated. Thanks.

It may be tricky getting it to boot from ext. hard drive. Not sure how Mac would work but I tried installing Slackware from an ext. drive and need to get the usb stuff going sometime during the install phase.

Maybe someone else have some ideas. Why not try a livecd version for awhile with Mac. I used Kubuntu livecd with my ppc mini mac and it ran pretty good. Everything worked except for my sound card.

I can easily boot from the external HD, it's getting FC6 ONTO that harddrive.

Huh, well, I got FC6 onto my external, but when I try to boot from it, I get the screen "Operating System Missing". And when I boot into mac with the external on, it tells me the disk in not readable (something I expected, though I also expected for the operating system to be on my external)

The PPC editions are for PowerPC (e.g. G4, G5) based Macs. Intel based Macs should use i386 if you have Intel Core Duo. If you have the newer Core2 Duo, which is 64 bit, you can try x86_64.
