I don't know about that, but I do know that the CD didn't burn correctly. The first Redhat CD is always bootable. If you burn it, and it doesn't boot, then you didn't burn it properly.
You may want to go into BIOS to make sure it is set to boot from the CDROM. Your best bet to make sure you download files correctly is to use FTP, and make sure you type binary before downloading the files.
