Field Name
This field controls which of the TaskFile register read or write accesses occur.
TaskFile read data is always 8 bytes in length, and unselected register data
are returned as 0x00. Register accesses occur in sequential order as outlined
here (0 to 7):
Bit 0 (0x3F6) Device Control/Alternate Status
Bit 1 (0x1F1) Features/Error
Bit 2 (0x1F2) Sector Count
Bit 3 (0x1F3) Sector Number
Bit 4 (0x1F4) Cylinder Low
Bit 5 (0x1F5) Cylinder High
Bit 6 (0x1F6) Device/Head
Bit 7 (0x1F7) Command/Status
This value indicates the maximum requested block size be in 512-byte
increments. This value must be set to the last value used for the ’Sectors per
block’ in the SET_MULTIPLE_MODE command. Legal values are 0, 1, 2, 4, 8,
16, 32, 64, and 128 where ‘0’ indicates 256 sectors per block. A command
failed status is returned if an illegal value is used in the ATACB.
These bytes contain ATA register data used with ATA command or PIO write
operations. Only registers selected in bmATACBRegisterSelect are required to
hold valid data when accessed. The registers are as follows.
ATACB Address Offset 0x05 (0x3F6) – Device Control
ATACB Address Offset 0x06 (0x1F1) – Features
ATACB Address Offset 0x07 (0x1F2) – Sector Count
ATACB Address Offset 0x08 (0x1F3) – Sector Number
ATACB Address Offset 0x09 (0x1F4) – Cylinder Low
ATACB Address Offset 0x0A (0x1F5) – Cylinder High
ATACB Address Offset 0x0B (0x1F6) – Device
ATACB Address Offset 0x0C (0x1F7) – Command
These bytes must be set to 0x00 for ATACB commands.
