[Ham-Linux] Unable to boot Linux CDs

[Dave 'Doc' Corio]

    Anyone have any idea why most of my Linux CDs will not boot on my 
new computer?

    The computer is a Gateway Core 2 Duo, running at 2.0 Ghz each 
processor, and has 2G of RAM.

    I have PSKMail, Harv's Hamshack Hack, Puppy, and a few others. All 
of them worked fine with my old computer, but Ubuntu is the only one I 
have now that will boot completely. The rest either give a message that 
a file can't be found (i.e., "Puppy not found on boot CD"), or they 
simply hang up during the boot process.

    The only difference I can see with this computer is the Core 2 Duo 
processor, and the fact that it has a SATA hard drive and not IDE. I 
think the CD drive is IDE.

    Very confused as to why all these CDs suddenly have problems.

Thanks in advance
Dave
