OK, this board has about gotten to me, I admit I am stupid when it comes to this SATA RAID stuff, this is my first socket 754 SATA board and SATA drive I have ever used. The ASUS manual is just like most motherboard manuals and that is, useless. I just put this system together and after finally getting the WD Raptor to be recognized, (don't know what I did though) I finally got XP installed, everything seems OK for a couple of days, then tonight I get the BSOD out of nowhere, and the machine reboots and I get the message something to the effect of "reboot and select proper boot device and press any blah blah" nothing has changed in my BIOS, so I updated the BIOS from the original version 1001 to the latest 1005 version, and still doesn't work, when I go into the BIOS and can sometimes get the BIOS to show the HDD the system will sometimes get to the Windows splash screen and then only to reboot again. My lack of knowledge is regarding the SATA ports on the board and which one is for what, there are 2 black ports in the center labeled SATA 1 and SATA2 then there are 4 red SATA ports on the bottom of the board labeled SATA RAID 1 thru 4. since I have only one SATA drive and am not using RAID, which port to use, and what setting in the BIOS needs to be enabled/disabled? Also what drivers are for what? Is this board a POS or what? I'm beginning to think so because I have done a lot of research and see that there does seem to be isolated SATA issues with them. ANY help would be greatly appreciated, I am about ready to order another board (if that is the problem) I just want a fast, reliable SATA socket 754 board, I am not over-clocking or using RAID.
