Not exactly. The bootsector written to the partition at default always boots
DOS1, but because DOS2 is installed, it runs the boot sector, but because a
processor flag it immediately returns to the DOS2 code, which attempts to
load MSXDOS2.SYS which executes the MSX-DOS 2 environment.
If you need to execute the code in the boot sector, you should remove the
RET NC (&HD0) code. Then it should work.
