Sector Count –

VV(Value volatile). If bit 0 is set to one, the device shall preserve the maximum values over power- up or hardware reset. If bit 0 is cleared to zero, the device shall revert to the most recent non-volatile maximum address value setting over power-up or hardware reset.

Sector Number –

Contains the native max address sector number (IDENTIFY DEVICE word 6) or LBA bits (7:0) value to be set.

Cylinder Low –

Contains the maximum cylinder low or LBA bits (15:8) value to be set. Cylinder High –

Contains the maximum cylinder high or LBA bits (23:16) value to be set. Device/Head –

If LBA is set to one, the maximum address value is an LBA value.

If LBA is cleared to zero, the maximum address value is a CHS value. DEV shall indicate the selected device.

Bits (3:0) contain the native max address head number (IDENTIFY DEVICE word 3 minus one) or LBA bits (27:24) value to be set.
