Re: need info on Serial ATA RAID
SATA controlllers weren't around when Microsoft designed Windows XP, so that's why XP cannot load a SATA driver like it does for IDE. You need to first figure out what SATA controller you have then find a matching driver. The best place to look would be your motherboard makers website.
VT8237 is a chipset number (not a mb. model)
SATA drivers are normally installed via F6 during XP install, requires a floppy drive. The other method is to integrate the sata drivers onto a custom XP install cd using a program like Nlite.
