Advanced Configuration And Power Interface BIOS Is Attempting To Create An Illegal Memory

This alert condition indicates that the ACPI BIOS is attempting to create an illegal memory. This condition can occur if a computer’s basic input/output system (BIOS) tries to write to a port in ACPI Machine Language (AML). This attempt causes Windows Server 2003 to prevent all access to that port.
