Bios does not recognize my Cdrom. Even though Windows XP does

Yes it is possible that your BIOS did not recognize your cd rom but your windows xp did, you can try to change your cable or switch with another cable change your slave IDE cable drive  to master drive  and vice versa then check again in your BIOS if its already recognized if not try to replace your IDE cable with a brand new IDE cable for sure the BIOS will not recognize your cdrom have your tried to check on your device manager.

If your cdrom is listed on the hardware you say you don't have any problem about using it so i don't care if your cdrom is not recognized by your BIOS as long as you can use it according to what it is suppose to do. You say that it can read your cd so try to repair by using your windows XP cd you can also try to use system restore by restoring your computer to the time it recognized your cdrom or you can scan your computer for some Trojan virus that can be the source of your problem but like what i say as long as you can use your cdrom accordingly i might not care even if my BIOS didn't recognized it.
