AHCI and RAID on HP Elite 8100 Business PCs

The process update an existing Windows XP image to be AHCI compatible is as follows:

1. Boot into WinPE.

2. Run MSDINST.EXE from OPK.

MSDINST.EXE is executed from a command line where the location for the .inf file containing the PnP

ID of the RAID/AHCI SATA controller of the target system and location of the Windows directory are

specified.

For example: Newmsd.inf has the PnP IDs and it is in the C:\AddAHCI directory. C:\Windows is the

location of the Windows directory. The command line is:

msdinst.exe c:\AddAHCI\newmsd.inf c:\windows /force

Newmsd.inf contents:

[SysprepMassStorage]

PCI\VEN_8086&DEV_2822&CC_0104 = C:\Compaq\MSD\Intel\iaStor.inf

PCI\VEN_8086&DEV_3A02&CC_0106 = c:\Compaq\MSD\Intel\iaahci.inf

PCI\VEN_8086&DEV_3A22&CC_0106 = c:\Compaq\MSD\Intel\iaahci.inf

PCI\VEN_8086&DEV_3B22&CC_0106 = c:\Compaq\MSD\Intel\iaahci.inf

Dev 2822 is the device ID for Intel(R) ICH8R/ICH9R/ICH10R/DO/PCH SATA RAID Controller

Dev 3A02 is the device ID for Intel(R) ICH10D/DO SATA AHCI Controller

Dev 3A22 is the device ID for Intel(R) ICH10R SATA AHCI Controller

Dev 2B22 is the device ID for Intel(R) PCH SATA AHCI Controller

3. Reboot the computer.

4. Enter F10 Setup and change SATA Emulation mode to AHCI.

5. Reboot the computer into Windows XP.

_GTF Support

The HP Elite 8100 Business PC supports _GTF (Get Task File) AHCI control method when in AHCI mode.

The Intel AHCI driver needs a registry key to enable _GTF for each port. This registry key has been added

with the Windows XP, Vista or Windows 7 image that ships with the HP Elite 8100 Business PC.

For customers using their own image, the following key is required:

HKLM\System\CCS\Services\iaStor\Parameters\Port[X]

name:GTF

value: 0=disabled 1=enabled

[X] represents the physical AHCI port of the connected drive to be _GTF enabled. To enable _GTF support

for all ports, set this value under each port (Port0, Port1...PortN).

Hardware

The HP Elite 8100 Business PC has the Intel Q57 Express/5 Series with PCH10 chipset, which supports an

AHCI capable Host Bus Adapter (HBA). This HBA supports ATA and ATAPI devices in both PIO and DMA

modes with NCQ as long as the device supports NCQ.

All hard drives shipped with the HP Elite 8100 Business PC are NCQ capable.
