Where are instructions to use PowerPc version of Live CD?

[mnut]

Hi

I downloaded the live CD last nite for PowerPC.  I'm on a dual G5 64  
bit, btw.  Where can I find instructions for using the disk?  I tried  
inserting the disk, rebooting while holding the C key and did come to  
a screen that was talking about booting Ubuntu, but commands that  
were suggested there didn't work.

Anyway, there was no read me file or instructions anywhere.  Can  
someone direct me to some help files?


Thanks

Mnut
