Yes, as Sp0iiLedBrAt has written you have to integrate >this< special 32bit Intel RST driver, which is working with just 1 driver named iaStor.sys. The XP installation would fail, if you would integrate any of Intel's RSTe drivers, because they use an addidtional SCSI driver named iaStorF.sys. Windows XP (32bit) is not able to manage this SCSI filter driver. No, you should have set the Intel SATA Controller to "AHCI" mode and boot off the Windows XP CD with integrated Intel RST driver I jhave linked above.You won't be able to get any Intel RSTe driverpack installed while running Windows XP (32bit). Hello. With your help I managed to integrate the X79 chipset AHCI drivers and install Windows XP without problems. I want to thank you for your help. I will recommend this useful forum.
