Hello. I have a simple question about the installation disc: it
didn't work on my iMac because it stuck on the second line with some
four letter word followed by 0C00. I'm not sure what that means, but
I think it is because it's trying to boot x86-32 when my iMac is
x86-64. Is there a separate installation disc for each processor
architecture? Thanks.

Mac OS X is still 32bit last I checked.  You're likely having an EFI related issue.
