Supports Command List Override (SCLO) — R/WO. When set to '1', indicates
that the HBA supports the PxCMD.CLO bit and it's associated function. When cleared
to '0', The HBA is not capable of clearing the BSY and DRQ bits in the Status register
in order to issue a software reset if these bits are still set from a previous operation.
Interface Speed Support (ISS) — R/WO. Indicates the maximum speed the SATA
controller can support on its ports.
2h =3.0 Gb/s.
Supports Non-Zero DMA Offsets (SNZO) — RO. Reserved, as per the AHCI Revision
1.0 specification
Supports AHCI Mode Only (SAM) — RO. The SATA controller may optionally
support AHCI access mechanism only.
0 = SATA controller supports both IDE and AHCI Modes
1 = SATA controller supports AHCI Mode Only
Supports Port Multiplier (PMS) — R/WO. ICH8 does not support port multiplier.
BIOS/SW shall write this bit to ‘0’ during AHCI initialization.
Supports Port Multiplier FIS Based Switching (PMFS) — RO. Reserved, as per the
AHCI Revision 1.0 specification.
NOTE: Port Multiplier not supported by ICH8.
PIO Multiple DRQ Block (PMD) — R/WO. The SATA controller supports PIO
Multiple DRQ Command Block
Slumber State Capable (SSC) — RO. The SATA controller supports the slumber
state.
Partial State Capable (PSC) — RO. The SATA controller supports the partial state.
Number of Command Slots (NCS) — RO. Hardwired to 1Fh to indicate support for 32
slots.
Command Completion Coalescing Supported (CCCS) — R/WO.
0 = Command Completion Coalescing Not Supported
1 = Command Completion Coalescing Supported
Enclosure Management Supported (EMS) — R/WO.
0 = Enclosure Management Not Supported
1 = Enclosure Management Supported
Supports External SATA (SXS) — R/WO.
0 = External SATA is not supported on any ports
1 = External SATA is supported on one or more ports
When set, software can examine each SATA port’s Command Register (PxCMD) to
determine which port is routed externally.

Reserved
Number of Ports (NPS) — RO. Hardwired to 5h to indicate support for 6 ports. Note
that the number of ports indicated in this field may be more than the number of
ports indicated in the PI (ABAR + 0Ch) register.
