I've been having reoccurring problems with the SATA controller on my board and I'm wondering if my setup is potentially at fault. I have a slightly awkward configuration as I am using two IDE hard drives, a single SATA-II hard drive and a SATA DVD-ROM drive. Here is how they are set up: Master IDE Drive (160GB) - Windows XP - [C:\] Slave IDE Drive (320GB) - [D:\] SATA port 1 Drive (500GB) - [E:\] SATA port 2 Drive (DVD Burner) SATA port 3 (empty/disabled) SATA port 4 (empty/disabled) For some reason I am getting timeouts that cause my video to fail after about 5 secs into a total freeze up. I look in the Event Viewer and I see the error caused by "atapi" which reads: The device, \Device\Ide\IdePort3, did not respond within the timeout period. I am having a hard time figuring out what that means or what device that message is referring to. There is no "IdePort3" there is only one on my board! I don't have RAID enabled, nor do I think it's possible, but I keep having this problem whenever the SATA devices are hooked up. I was looking in BIOS and there is something called "SATA DMA Transfer" which is enabled. Would that have anything to do with this? I could really use some help with this. Thanks in advance for any input.
