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 - TRANSLATE RBA TO ABA AX = 1C0Eh CH = low 8 bits of cylinder number CL = sector number, high two bits of cylinder number in bits 6 and 7 DH = head number DL = drive number (80h,81h) ES:BX -> ABA number Return: CF set on error CF clear if successful AH = status (see #00234 at AH=01h) Note: ABA (absolute block address) format can be found in IBMInternational Busiuness MachinesInternational Busiuness Machines) A hardware, software and other service technology company founded in 1911.
