I've had my Opteron 170 based computer for about 18 months. I never had serious problems with it before.Recently I had to reinstall my 4 SATA and 3 IDE hard drives.
When I did this Windows XP would start to boot and then restart. I disabled the auto-restart and got a blue screen with "machine check exception". Windows would only boot correctly in safe mode. I reinstalled clean copies of XP on various hard drives and after the installations finished the first boot sequence would always crash at the same place and give the same error.
Here is what Ive already done:
-Made a bootlog in which it loaded all drivers up unti "ACPI MULTIPROCESSOR PC" and that is where is crashed
-changed every BIOS setting I could think of.
-Flashed the BIOS with the newest version
-Disconnected all drives but one and tried to install Windows on that one drive.
-None of these worked at all. I did stumble across a partial solution by forcing XP to install from an IDE drive with no SATA connected *and* forcing it to use "Standard PC" HAL instead of "ACPI Multiprocessor" and then connect the SATA drives later
-Obviously this meant only one of my cores worked in Windows so was slow but it did work for a few hours and then somehow it formatted the drive it was on. I am trying to recover the partition now but in addition to the slowness, some of the IDE drivers wouldn't work in this mode so it isn't very useable.
So I'm really at my wits end trying solve this. I would like to get XP to work with the proper HAL but nothing I've tried works.
thanks for any help...
