GTT Graphics Memory Size (GGMS):
This field is used to select the amount of Main Memory that is pre-
allocated to support the Internal Graphics Translation Table. The
BIOS ensures that memory is pre-allocated only when Internal
graphics is enabled.
00: No memory pre-allocated. GTT cycles (Mem and IO) are not
claimed.
01: 1 MB of memory pre-allocated for GTT.

NOTE: This register is locked and becomes Read Only when the
Graphics Mode Select (GMS):
This field is used to select the amount of Main Memory that is pre-
allocated to support the Internal Graphics device in VGA (non-
