This happens with disturbing frequency on my machine, the BIOS often
doesn't detect a CD or DVD in the player and jumps to the harddisk
directly. It's either a BIOS bug or a problem with my DVD player, I
haven't decided which yet
It is theoretically possible to change BIOS settings from inside an
operating system, for example my thinkpad has a program (for windows)
which changes the password/firgerprint settings. This could be made to
change any BIOS setting, including the boot order. But as far as I'm
aware, there is no such functionality in linux at this time
