Intel SATA AHCI Controller Driver:
ftp://ftp.hp.com/pub/softpaq/sp36001-36500/sp36132.exe

Installation Instructions
1. Download the SoftPaq .EXE file to a directory on your hard drive.
2. Execute the downloaded file and follow the on-screen instructions. A diskette containing the driver is created, and the driver files are also made available at c:\swsetup\sp36132. If you choose to cancel diskette creation, you will need to copy the driver files to the chosen media.

To use the diskette during a new operating system installation, complete the following steps (choose the procedure that matches the operating system you are running).

For Microsoft Windows XP:
NOTE: A USB diskette (floppy) drive is required to use this driver. If an external USB diskette drive is used, ensure that it is plugged into the system before starting Step 1.

1. Insert the operating system CD, and Power On the notebook to boot from the CD.
2. At the very beginning of the operating system installation, the following prompt is displayed at the bottom of the screen: "Press F6 if you need to install a SCSI or RAID driver...."When the prompt is displayed, press F6.
3. Later in the operating system installation, you are notified that a mass storage device could not be detected. When this notification occurs, press S (S=Specify Additional Device).
4. When prompted, insert the diskette that was created from the SoftPaq file, and then press Enter.
5. Select "Intel 82801HEM/HBM SATA AHCI Controller (Mobile ICH8M-E/M)" and press Enter.
NOTE: At this point, the following prompt MAY be displayed, depending on the version of your operating system CD. If the prompt is displayed, press Enter to use the default Windows driver and continue, if it is not displayed, continue with next step 6. The prompt reads as follows: Windows already has a driver that you can use for "Intel 82801HEM/HBM SATA AHCI Controller (Mobile ICH8M-E/M)". Unless the device manufacturer prefers that you use the driver on the floppy disk, you should use the driver in Windows. S=use the driver on floppy ENTER=use the default Windows driver
6. Continue with the operating system installation, as prompted.
NOTE: If a problem is encountered when using the external USB floppy drive,
refer to Microsoft Knowledge Base Article 916196: "A connected USB floppy
disk drive does not work when you press F6 to install mass storage drivers
during the Windows XP installation process."
