INT 13 - FIXED DISK - PARK HEADS ON 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. DRIVE (XT286IBM PC XT/286,PSIBM PS/2, any model)
