INT 13 U - ESDI(Enhanced Small Device Interface) A disk drive interface type which was briefly popular before IDE took over.	 An ESDI drive can transfer data between the drive and controller at 10, 15, or 20 megabits per second, which is faster than an MFM or RLL controller but slower than what is possible with an IDE or SCSI drive.	 See also IDE. FIXED DISK - GET POS INFORMATION
	AX = 1C0Ch
	ES:BX -> buffer for POS Information Status Block (see #00262)
Return: CF set on error
	CF clear if successful
	AH = status (see #00234 at AH=01h)
