XP Blocking CD Boot

["Thomas H. George" <lists@tomgeorge.info>]

I built a new computer with two hard drives and installed XP Home 
Edition on the first drive.  The second drive contains my Debian system 
- kernel 2.6.17 and Testing.  I intended to use disc 1 of a Sarge 
installation set as a rescue disk to access hdb and run lilo to convert 
this box to a dual boot box.

After XP was installed the system will no longer boot from a CD.  Even 
after I entered BIOS setup and changed the first, second and third boot 
choices to CDROM the system still persists in booting from the hard drive.

What can I do to regain control?
