	AX = 057Fh
	SI = 324Dh ("2M")
	CH = track number
	DH = head number
	DL = drive number
	ES:BX -> boot sector of future 2M diskette
Return: CF set on error
	CF clear if successful
	AH = status (see #00234)
Program: 2M is a TSR(Terminate and Stay Resident) A program which remains in memory after terminating in order to provide services to other programs or the user.  The name comes from the name of the DOS function call used to remain in memory after termination. developed by Ciriaco García de Celis to support
	  non standard diskettes with 820-902/1476-1558K (5.25 DD/HD)
	  and 984-1066/1804-1886K/3608-3772K (3.5 DD/HD/ED)
InstallCheck: must search for a "CiriSOFT:2M:1.3" or "CiriSOFT:2MX:3.0" or
	  similar (recomended ":2M:", ":2MX:", or ":2MB:" substrings) in the
	  CiriSOFT TSR(Terminate and Stay Resident) A program which remains in memory after terminating in order to provide services to other programs or the user.  The name comes from the name of the DOS function call used to remain in memory after termination. interface
Notes:	it is not necessary to call AH=17h or AH=18h first (will be ignored)
	the diskette format must always begin on cylinder 0 head 0
	the boot sector can be obtained from an already-formatted 2M diskette
	  (by calling AH=02h with head number 00h in 2M v1.x and with head
	  number 80h for 2M v2+)
	since 2M v2.0, the BOOT sector is emulated using the first physical
	  sector of FAT2; the second-sixth physical sectors of FAT2 in HD or ED
	  diskettes store the SuperBOOT code. To skip the FAT2 emulation (using
	  FAT1) of 2M, in order to read the SuperBOOT code, head number must be
	  80h-81h instead 0-1 (bit 7 active) in standard read/write functions.
	  This lets diskcopy programs format 2M target diskettes copying
	  SuperBOOT code. If the target diskette is already 2MF formatted
	  (containing boot code) this trick it is not necessary.
	when using STV technology (offset 65 of boot sector equal to 1) it is
	  necessary to write the full track before formatting (except track 0
	  side 0) to complete the format and skip future CRC errors on read; in
	  track 0 side 1 the head used must be 81h instead 1. Diskcopy programs
	  may do a format-write-verify sequential phases to improve performance
