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.
10: Reserved
11: Reserved
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-linear)
and Native (linear) modes. The BIOS ensures
that memory is pre-allocated only when Internal
graphics is enabled.
0000:
(IGD) does not claim VGA cycles (Mem and IO),
and the Sub-Class Code field within Device 2
function 0 Class Code register is 80.
0001:
pre-allocated for frame buffer.
0011:
pre-allocated for frame buffer.
BIOS Requirement: BIOS must not set this field
to 000 if IVD (bit 1 of this register) is 0.
Reserved ()
IGD VGA Disable (IVD):
0: Enable. Device 2 (IGD) claims VGA memory
and IO cycles, the Sub-Class Code within Device
2 Class Code register is 00.
1: Disable. Device 2 (IGD) does not claim VGA
cycles (Mem and IO), and the Sub- Class Code
field within Device 2 function 0 Class Code
register is 80.
BIOS Requirement: BIOS must not set this bit
to 0 if the GMS field (bits 6:4 of this register)
pre-allocates no memory.
This bit MUST be set to 1 if Device 2 is disabled.
Reserved ():
