Description:
PCH EG20T SATA does not support an IDE interface that is compatible with
Legacy. Windows XP* SP3 does not contains the required SATA AHCI
driver natively hence you must follow the below instructions to install the
PCH EG20T SATA AHCI driver during the installation of Windows XP* SP3.
1. Copy the files in 'FD_Inst_WinXP' in the SATA driver package to the root of
a Floppy Disk.
iohsata.cat
iohsata.inf
iohsata.sys
txtsetup.oem
2. Insert the floppy disk prepared in step 1 into the USB floppy drive and
connect it to the target machine via USB port.
3. Insert Windows XP* SP3 installer into the CD-ROM and boot from the CD-ROM
to kick start Windows XP* SP3 installation
4. Press <F6> to add further SCSI/RAID drivers when prompted during the very
early stage of windows installation.
5. Press <S> to add an additional SCSI device.
6. Select the correct driver (PCH EG20T SATA AHCI Controller for Windows XP)
and press <ENTER> to continue the installation. This will install the
PCH EG20T SATA AHCI controller driver.
7. Finish the WindowsXP installation according to your needs.
Some USB Floppy drivers are not supported during F6 installation. See
details at http://support.microsoft.com/kb/916196
