Details of Chipset Features Setup
Auto Configuration (60ns DRAM)
The default setting of 60ns DRAM sets the optimal timings for items 2 [DRAM
Read Burst (B/E/F)] through 6 (MA Wait State) 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 because 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.
