11.1.2.8 Drive/Head (LBA 27-24) Register
The Drive/Head register is used to select the drive and head. It is also used to select LBA addressing instead of
cylinder/head/sector addressing. The bits are defined as follows:
Symbol
Function
LBA
LBA is a flag to select either Cylinder/Head/Sector (CHS) or Logical Block Address mode (LBA).
When LBA=0, Cylinder/Head/Sector mode is selected. When LBA=1, Logical Block Address is
selected. In Logical Block mode, the Logical Block Address is interpreted as follows:
LBA7-LBA0: Sector Number register D7-D0.
LBA15-LBA8: Cylinder Low register D7-D0.
LBA23-LBA16: Cylinder High register D7-D0.
LBA27-LBA24: Drive/Head register bits HS3-HS0.
DRV
DRV is the drive number. When DRV=0 (Master), Master is selected.
When DRV=1 (Slave), Slave is selected.
HS3
When operating in the Cylinder, Head, Sector mode, this is bit 3 of the head number.
It is Bit 27 in the Logical Block Address mode.
HS2
When operating in the Cylinder, Head, Sector mode, this is bit 2 of the head number.
It is Bit 26 in the Logical Block Address mode.
HS1
When operating in the Cylinder, Head, Sector mode, this is bit 1 of the head number.
It is Bit 25 in the Logical Block Address mode.
HS0
When operating in the Cylinder, Head, Sector mode, this is bit 0 of the head number.
It is Bit 24 in the Logical Block Address mode.
