9.1.5.8 Drive/Head (LBA 27-24) Register (Address 1F6H[176H]; Offset 6)
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
Bit 7
This bit is set to 1.
Bit 6
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.
Bit 5
This bit is set to 1.
Bit 4 (DRV)
DRV is the drive number. When DRV=0, drive (card) 0 is selected. When DRV=1, drive
(card) 1 is selected. The CompactFlash card is set to be Card 0 or 1 using the copy field
(Drive #) of the PCMCIA Socket & Copy configuration register.
Bit 3 (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.
Bit 2 (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.
Bit 1 (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.
Bit 0 (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.
