Actually, the MBR does not contain any code per se.  The purpose of the 
MBR is to tell the BIOS
how to handle booting the disk, if it is bootable.  Every bootable disk 
must have an MBR!  Non-
bootable disks do not have MBRs.  The MBRs consist entirely of data and 
instructions, not code.
Hope this clears up any misconceptions.
