		BIOS table, but not register compatible, and therefore

		not present in CMOS.

		Furthermore, we will assume that our ST-506 drives

		<if any> are the primary drives in the system, and 

		the ones reflected as drive 1 or 2.

		The first drive is stored in the high nibble of CMOS

		byte 0x12, the second in the low nibble.  This will be

		either a 4 bit drive type or 0xf indicating use byte 0x19 

		for an 8 bit type, drive 1, 0x1a for drive 2 in CMOS.

		Needless to say, a non-zero value means we have 

		an AT controller hard disk for that drive.

		Currently the rtc_lock is a bit academic since this

		driver is non-modular, but someday... ?         Paul G.
