- MOVROM copies the BIOS to RAM, makes it resident, and repoints
- all BIOS interrupts to the copied code, thus allowing any debugger
- operations to be preformed.
- MOVROM must be executed before any resident utilities are installed
- because such utilities repoint BIOS interrupts to themselves. When
- MOVROM exits, it displays the segment where it copied the ROM code;
- the offsets are the same as in the original BIOS listing.
