* DragonDOS BOOT loads sectors (numbered from 0) 2-17 (3840 bytes) into
* RAM at location 9728. The first two bytes of sector 2 must be ASCII 'OS'
* for this to work. It then jumps to 9730 and begins execution.
*
* The boot code switches into RAM mode, and copies the entire section to
* $F000 and jumps to $F04F.
* The 3840 bytes contain a few bytes to do the RAM mode switch, then
* immediately after comes the kernel modules; OS9, OS9p2, Init and Boot
* The rest of the bootstrap is in the OS9Boot file. The disk head at LSN0
* contains the LSN of the bootstrap file in field DD.BT.
