I thought that one of the function keys pressed during power up
brings up a bios menu that lets you select which drive to boot from.
If you enter into bios setup, and select boot order, you can select
the CD drive first, driveA second, driveB third, and PEX boot fourth.
So, during power up one of the function keys lets you select which
of these to boot from.
