BIOS can't read ISO?!

I was all set to load up openSUSE 11.0 on a server but when I tried to boot from CD a message came up saying that my BIOS has to be upgraded to boot the ISO?!

The system has an old copy of Fedora and I was going to rebuild it from scratch with a new Suse install.

Is there someway I can boot Fedora and then mount the ISO and install from there? Using what commands? Or is there another way to install Suse in this instance?

couple of things:

1 ) did you burn the iso as an image or just iso ?
2 ) Smart Boot Manager is the tool i use for recalcitrant boot devices
