ERR_UNKNOWN_DEVICE - the HAL was unable to identify the display
controller. Returned when pID returns ID_UNKNOWN.
Retrieves the HAL library version information. The return values are ASCII strings.
A typical return would be: “1.01 B 5” - HAL version 1.01, 'B' is the beta designator,
this example would be Beta 5. If pStatus is NULL then pStatusRevision should be
NULL too.
