Routine Description:
Initialize the generic memory test.
Arguments:

function if not any non-tesed memory found means
that the memory test driver have not detect any
non-tested extended memory of current system.

Routine Description:

DIMMs be disabled.
ErrorOut - Any time the memory error occurs, this will be TRUE.
IfTestAbort - Indicate if the user press "ESC" to skip the memory
test.

already go through.
