Chipset Features Setup
This “Chipset Features Setup” option controls the configuration of the board’s chipset.
Control keys for this screen are the same as for the previous screen.
NOTE:
SETUP Defaults are noted in parenthesis next to each function heading.
Details of Chipset Features Setup
Auto Configuration (60ns DRAM)
The default setting of
60ns DRAM
sets the optimal timings for items 2 through 6 for
60ns DRAM modules.
If you are using 70ns DRAM modules, you must change this
item to
70ns DRAM
.
See section III for DRAM installation information.
DRAM Refresh Type (RAS Only)
Leave on default setting of
RAS Only
as this is the current standard.
CPU-to-PCI IDE Posting (Enabled)
Leave on default setting of
Enabled
so that the CPU to PCI IDE posting cycles are
treated as normal I/O write transactions.
USWC Write Posting (Enabled)
Leave on default setting of
Enabled
to allow USWC write posting during
I/O bridge access.
CPU-to-PCI Write Post (Enabled)
The default setting of
Enabled
will increase the efficiency of the PCI bus and speed
up the execution in the processor.
PCI-to-DRAM Pipeline (Enabled)
The default of
Enabled
will increase the bandwidth of the path between the
PCI and the DRAM to enhance the PCI bus efficiency and DRAM accessing.
PCI Burst Write Combining (Enabled)
The default setting of
Enabled
will increase the efficiency of PCI bus by combining
several CPU to PCI write cycles into one.
VGA performance is increased by this
action.
