Just setting up a new PC with an ASUS P5Q Pro, which has a Sil5723 RAID chip. Took me a while to figure out how to use it... a few ASUSisms....
"Drive Xpert Technology" = RAID
"Super Speed" = RAID0
"EZ Backup" = RAID1
Anyway... I chuck the Windows XP x64 disc in... oops dont have RAID drivers ready for it... Then to my amazement, windows detects the two hard drives as a single disc, unlike any of my previous RAID chips (ICH9R, nForce 3, nForce 4, HighPoint 2320), which would all show up as separate discs if I didn't press F6 and give it the drivers.
What's going on here, surely the Windows disc can't have drivers for it as it's too new?
