After upgrading from ME to XP Home I see event log error.

"Event ID 5: AMLI: ACPI BIOS is attempting to write to an
illegal I/O port address (0x70) wihich lies in the 0x70 -
0x71 protected address range."

Any suggestions?
 
CAUSE
This behavior may occur if your computer's basic input/output system (BIOS) tries to write to one of the earlier ports by using an AML [Advanced Configuration and Power Interface (ACPI) Machine Language] System IO operation region. Your try may be blocked by Windows XP because accessing these ports by using this mechanism is deemed dangerous and can cause system instability. This feature is designed to improve the stability of your computer's operating system.
STATUS
This behavior is by design.

Contact the BIOS vendor for a possible BIOS update. For more information see the following Microsoft Web site:
