| Explanation | |
|
The Advanced Configuration and Power Interface (ACPI) basic input output system (BIOS) software routines test hardware at startup and start the operating system. These routines incorrectly attempted to access hardware resources and the operating system at the same time. This type of access cannot be synchronized and could cause system instability. This error is usually caused by an obsolete BIOS. |
