I've downloaded the Win8 beta and this morning I disconnected all the\ncurrent drives from my P5Q Pro Turbo, plugged in a spare, and installed\nWindows 8 on it under AHCI. The installation went smoothly and\neverything seemed to be working.\n\nThen I installed the ICH10 driver that I must use under Windows 7 in\norder to make the board's Drive Xpert feature work. (It's a quasi-RAID\nfeature that combines drives connected to the board's orange and white\nSATA sockets.) I had to use Windows compatibility mode to install\nanything from the P5Q's installation disk.\n\nThen I tried plugging in my other drives: one 3-gig HDD, two 1-gig HDDs\nrunning together under Drive Xpert, and a 1.5-gig HDD. Windows 8\npromptly croaked.\n\nActually, when I tried to boot with all the drives connected, I got a\nwarning screen saying I had a "DPC Watchdog Violation" and that I should\nlook it up if I wanted to know what that meant. So after re-booting\nwith the drives disconnected I looked it up and found nothing helpful.\nMost people are seeing it pop up while running, as some sort of BSOD\nthat appears unexpectedly. I couldn't get that far; I simply couldn't\nget Win8 to run, to get past the Violation screen at boot.\n\nI did a little more troubleshooting. I discovered that I'd see the\nViolation screen at boot with either the 3-gig drive connected by\nitself, or with it disconnected and just the two 1-gig drives connected\nas a pair.\n\nI didn't see the Violation at all with just the 1.5 gig drive connected.\nIn fact, with just that drive connected Win8 would boot just fine.\nBut...it wouldn't recognize the drive. BIOS could see it, but not Win8.\n\nWhen I took the Win8 drive out of the system and replaced it with my\nWin7 boot drive (SSD) with all the drives plugged in, everything went\nright back to normal. I'm running Win7 just fine. So what's up with\nWin8? Anybody had any experience with it yet? Thanks.
