I got an error message in event viewer as follows:

Description:

Not to many here really up on error messages with XP most are still experimenting but they will come by and give some info.this is all I can offer.

This behavior can occur if your computer's basic input/output system (BIOS) attempts to write to a port in AML [Advanced Configuration and Power Interface (ACPI) Machine Language]. This attempt causes Microsoft Windows XP to prevent any access to that port. This feature has been 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: http://www.microsoft.com/HWDEV/Onnow/BIOSAML.htm

Go to the link and it describes almost the exact numbers you describe.

Good Luck And Welcome to PC Guide.

Dear YODA74
Thank you very much for your information.

Is ACPI en-abled or dis-abled in CMOS(BIOS)?


Luck.
