Add-on cards sometimes have an option to disable their own bios which 
you should do if you don't want to boot from them.  Usually if you boot 
from a drive it remains mapped into the first position but if you don't 
it will be later in the list.  The motherboard bios may also give you an 
extensive choice (or not...) about what order to check for bootable 
devices.  'Dmesg' will show the linux device probe sequence and 
discovery order, assuming things worked well enough to get that far.
