2) Why are all of my devices (Sound card, video Card, Promise Controller) sharing 1 IRQ (IRQ9, the same as the ACPI controller)????. This is normal for winXP. If I remember right, WinXP uses what is called "virtual" IRQ's. (got that one from the OS's forum). Mine shows up the same way as yours as in seperate IRQ's shown in BIOS, but WinXP gives it all IRQ 9. As far as the drivers go, I can't help you out there as I am not using RAID 0 with my A7V133. Just usiing it as ATA100 controller for my HDD and ZIP drive (the only place i can put my zip as the 686B southbridge is a pile of doodoo w/Zips) and I am using the XP installed promise drivers..I am surprised that WinXP didn't install drivers for you during XP setup.
