I am trying to write a system commander type program. For those who are unfamilar with this type of program, it allows you a nice menu approach to selecting 1 of multiple operating systems.

I am stuck at 1 point though, getting my program to run first; ie. before the OS kicks in. Does anybody know how to get your program to be the one that is run first at system startup.

I think the answer is something to do with writing to the boot sector.

Thanks in advance,
