Hello

I have a big Problem with my Compaq CQ71-412EG! When i want to start Windows 7 i got a 0xA5 Error.

No i install Windows XP without ACPI but i cant upgrade my Bios with the Download from the HP Website.

What can i do now? My Bios Version is F20. The newest one is F23

Here is the Download link for the newest one:
