Internal Graphics Disable
(INTGFXDIS):
0: There is a graphics engine within the
processor. Internal Graphics Device
(Device #2) is enabled and all of its
memory and I/O spaces are accessible.
Configuration cycles to Device 2 will be
completed within the processor. All non-
SMM memory and IO accesses to VGA
will be handled based on Memory and
IO enables of Device 2 and IO registers
within Device 2. A selected amount of
Graphics Memory space is pre-allocated
from the main memory based on
Graphics Mode Select (GMS in the
processor UNCORE Control Register).
Graphics Memory is preallocated above
TSEG Memory.
1: There is no graphics engine within
the processor. Internal Graphics Device
(Device #2) and all of its memory and I/
O functions are disabled. Configuration
cycle targeted to Device 2 will be passed
on to DMI. In addition, all clocks to
internal graphics logic are turned off.
DEVEN [4:3] (Device 0, offset 54h)
have no meaning. Device 2 Functions 0
and 1 are disabled and hidden.

Overlapped scheduling disable
(OSD):
Controls whether the Memory Controller
is capable of overlapping micro-
commands (e.g., PCHG and ACT) for
subsequent commands ahead the
current Read or Write in progress.
0: Capable of Overlapped Scheduling
1: Not Capable of Overlapped
Scheduling.
