	\|CPM or \|CPM,<drive> - Boot CPM from drive A, or chosen drive. A=0,B=1,D=3,E=4,F=5,G=6. Can boot from D,E,F,G if HD is detected. Can't boot from drive C.		\|CPM or \|CPM,<drive> - Boot CPM from drive A, or chosen drive. A=0,B=1,D=3,E=4,F=5,G=6. Can boot from D,E,F,G if HD is detected. Can't boot from drive C.

			== Booting CPM ==

			The process to boot cpm is the same on floppy discs and hard disk and uses a common read sector function that re-directs to low-level functions based on the chosen drive.

			Using \|CPM,<drive> you can define which drive to boot from.

			When \|CPM is executed:
			* on 2.10 and later, the hard disc is detected and be4b is set to ff if detected, 00 if not detected.
			* the bios jumpblock is copied to be80 from c07b.
			* iobyte (0003) is set to 81
			* the current drive is written to &0004. A = 0, B = 1, D=3 etc.
			* ad33 'enter firmware' is setup.
			* the XDPB is queried to find the location of the boot sector
			* the boot sector is loaded to &100.
			* if the boot sector has code, then the boot sector is executed from &100.
