The head number of the first sector to be transferred. ( L = 0 )

In LBA mode, this register specifies LBA bits 24-27 to be transferred. ( L = 1 )

The retry bit. If set to one, then retries are disabled.

Input Parameters From The Device

Sector Count

The number of requested sectors not transferred. This will be zero, unless an unre-
coverable error occurs.

Sector Number

The sector number of the last transferred sector. ( L = 0 )

In LBA mode, this register contains current LBA bits 0 - 7. ( L = 1 )

Cylinder High/Low

The cylinder number of the last transferred sector. ( L = 0 )

In LBA mode, this register contains current LBA bits 8 - 15 (Low), 16 - 23 (High).
( L = 1 )

The head number of the sector to be transferred. ( L = 0 )

In LBA mode, this register contains current LBA bits 24 - 27. ( L = 1 )
