Vista and XP Downgrades, Pt. 2: SATA RAID

The deluge has begun. We are seeing people walking into the store with new PC's and a retail box of XP in their hands and it can only mean one thing.

We have come upon some interesting kinks in the upgrade process. Yesterday's treat: Some of the new HP Presario machines with Intel chipsets are shipping with single SATA disks but with the RAID mode turned on. This causes all kinds of problems for the XP installer which does not have drivers for these new Intel Matrix storage chipsets.

We fought with it a lot. Of course most new PC's do not have floppy disks, so the traditional process of downloading the XP drivers to a floppy and pressing F6 during the XP installation start-up is immensely complicated.

Our solution which has worked so far: Go into the PC BIOS, and set the default SATA operations mode from RAID to IDE. This will emulate a traditional single-IDE disk drive and the XP installer will run.
