Datasheet

The retry bit. If set to one, then retries are disabled. When write cache is

enabled, They are ignored. (Ignoring the retry bit is in violation of ATA-3.)

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

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

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

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

(L=1)

Cylinder High/Low

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

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

Sector Number

The number of continuous sectors to be transferred. If zero is specified, then

256 sectors will be transferred.

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)

Cylinder High/Low

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

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

Sector Number
