I'm installing windows xp pro on my new computer that came with windows 7 ultimate.
When starting setup with the xp disc i get an error sayin that acpi.sys may be corrupt
and press any key. Setup has failed it tells me. Do I need to update the BIOS before starting to
get past this? Does the BIOS need to be updated for windows XP to run? If so how do I update the BIOS before
installing XP? If this is not BIOS related how do I fix this? Thank you!
