- What you are attempting to do is intrinsically impossible.
-
- Think about it: what will happen to your program when you reboot the computer?
-
- Further, I'm not aware of *any* PC BIOS that supports booting from the B drive. Switching your A and B drives
- *cannot* be done solely through software, as you must either (1) swap cable connections on the drives, or (2) change
- jumper settings on both drives; if the drives have different capacities (e.g. 1.2 MB and 1.44 MB), you must also alter
- the BIOS settings for the drives (which can be done through software).
-
- What is the problem you are trying to solve?
