COHERANT is another OS that uses this method. Actually there are any
number of other a-v solutions that will do as well (such as my own
FixMBR which can produce a small executable file that will restore the
original MBR) but FDISK /MBR has three great advantages:
a) It is a no-brainer.
b) Everyone who has DOS 5.0 has it.
c) It will *not* lose/change the partition table.

Given that you know FDSIK /MBR uses "basic, boring code" you probably also
know how to use DEBUG to repair most anything that FDISK /MBR can, but for
those who need to ask - K.I.S.S.

ps It is my understanding (David ?) that OS/2 uses selection through a 
   replacement of the DBR (OBR ?) *not* the MBR and requires a more complex
   approach e.g. You boot. If the wrong OS comes up, you instruct a program
   to replace the DBR with the correct one then you boot again. Hopefully
   this time the correct OS comes up. Only IBM...
