Well, I ran into a strange problem today. It is BSOD stop 0x000000A5, "BIOS is not fully ACPI compliant" related.
Background: I am running an A8N32-SLI deluxe mobo with BIOS version 14.09, a x2 4400+ processor and 2GB of RAM. I have 2 seagate 320GB SATA hard drives, one with XP pro and one with Vista ultimate installed. This is all powered by an Antec 550W power supply and displayed through an EVGA 8800GT. The rig runs very smoothly.
Today I picked up a seagate 500GB SATA hard drive (firmware up to date), installed it into my rig and loaded up Windows 7 (64 bit). The install went well and windows 7 is up and running.
When I went back to check my other OS's, I encountered a problem. I could boot into Vista with no issue but when I tried booting into XP I encountered a blue screen of death. I found that if the 500GB drive or the drive with Vista is disconnected, XP boots fine. Having all 3 drives connected triggers the BSOD.
I tried switching the drives between the 4 SATA ports but no combination would make XP work with 3 drives connected. Vista and Windows 7 worked in all combinations.
In the short term I have disconnected the drive with Windows 7 since I use XP more often.
By the way, I use F8 at boot and select which drive/OS I want to start.
