I must be doing something basic wrong as I cannot get this to work so I built XP on the Vostro 1300 Dell laptop on which I am having problems. I then tried to change the HAL through device manager. As expected it said the ACPI (Not the UniProcessor) was a valid compatible HAL thus allowed me to change to it. HOWEVER, following the reboot the machine BSOD's with the same error that it does when I try to image it. Can anyone explain why it is doing this? Why does it say its a Valid HAL then not allow to boot up in it?
