IC-7 Bios problem?

I have the latest IC-7 bios installed, and all of sudden the "Hard Disk Boot Priority" is starting to change the order by itself.
Has anyone ever had this sort of problem?
Any solutions?

yes I had the same problem,hav e 2 hard drives and the slave sometimes is not reginized. So what I did was to disable my slave hard drive in bios.........works find and xp still see the drive.Try that and see.............
