7.2 CD won't boot

[John Nielsen.]

Hi guys,

My 7.2 Release Disc 1 won't boot.  I get the following and nothing more:

CD Loader 1.2

Building the boot loader arguments
Looking up /BOOT/LOADER... Found
Relocating the loader and the BTX

I'm running on a Intel SE7501BR2, single Xeon, 2GB.  I have burned a
second CD and swapped the CD drive, cable and RAM, all to no avail.  I
have a RR1520 RAID controller, but removed that as well.  On-board SCSI
controller and serial ports have been disabled, too.  Nothing seems to
make a difference.

What on earth could be going on?

Thanks,

Brad Waite
