bootselect(8):

   Bootselector  The bootselecting MBR contains configurable code that will
                 present the user with a simple menu, allowing a choice be-
                 tween partitions to boot from, and hard disks to boot from.
                 The choices and default settings can be configured through
                 fdisk(8).

   ...

   Keys F5 through F10 will boot from harddisks 0 through 5 (BIOS numbers
   0x80 through 0x85). Booting from a drive is simply done by reading the
   MBR of that drive and executing it, so the bootcode present in the MBR of
   the chosen drive determines which partition (if any) will be booted in
   the end.

fdisk -B
