Booting off of the RHEL4.6-ia64-ES-disc1.iso

[Al Sparks]

I downloaded the RHEL4.6-ia64-ES* ISO files, and burned the RHEL4.6-ia64-ES-disc1.iso to a CD.

I attempted to boot off of it and it simply doesn't.

I used Windows Sonic DigitalMedia Plus v7, using the Copy -> Burn Image option.

What am I doing wrong?
