INT 18H: ROM-BASIC
This vector (at 0:0060) has the entry point for the ROM-BASIC interpreter
which is found only on IBM-logoed computers. Clones do not have BASIC in
ROM and must use a separate program, usually QBASIC or GWBASIC.
If ROM-BIOS could not get a disk to boot, it takes this vector. This
makes it possible for a ROM-Scan external ROM module to alter this vector
to point to itself, thus giving itself control if the disks fail or are
not present.
