determines the optimal delay),
2 SCLKs or 3 SCLKs
.
Note: The Optimal
default setting is Auto and the Fail-Safe default setting is 3
SCLKs.
Power Down SDRAM
BX supports SDRAM power down mode to minimize SDRAM power
usage. The settings for this option are
Enabled
or
Disabled
. The
Enabled
setting enables the SDRAM Power Down feature.
ACPI Control Register
The settings for this option are
Enabled
or
Disabled
. Set this option to
Enabled
to enable the ACPI (Advanced Configuration and Power Inter-
face) control register.
Gated Clock
Signal GCLKEN enables internal dynamic clock gating in the 82443BX
when a AGPset "IDLE" state occurs. This happens when the 82443BX
detects an idle state on all its buses. The settings for this option are
Enabled
or
Disabled
. The
Enabled
setting enables the gated clock.
Graphics Aperture Size
This option specifies the amount of system memory that can be used by
the Accelerated Graphics Port (AGP). The settings are
4 MB
,
8 MB
,
16
MB
,
32 MB
,
64 MB
,
128 MB
, or
256 MB
.
Search for MDA (Monochrome Adapter) Range (B0000h-B7FFFh)
R e s o u r c e s
Legacy support requires the ability to have a second graphics controller
(monochrome) in the system. In an AGP system, accesses in the normal
VGA range are forwarded to the AGP bus. Since the monochrome
adapter may be on the PCI (or ISA) bus, the 82443BX must decode
cycles in the MDA range and forward them to PCI. The settings for this
option are
Yes
or
No
. Set this option to
Yes
to let AMIBIOS search for
MDA resources.
AGP Multi-Trans Timer (AGP Clks)
This option sets the AGP multi-trans timer. The settings are in units of
AGP clocks:
32
,
64
,
96
,
128
,
160
,
192
, or
224
.
AGP Low-Priority Timer
This option controls the minimum tenure on the AGP for low priority data
transaction for both read and write. The settings are
Disabled, 32, 64,
96, 128, 160, 192 or 224
.
