Chipset Features Setup
Auto Configuration
This item auto configure the following items: DRAM RAS# Precharge time,
DRAM R/W Leadoff Timing, Fast RAS to CAS Delay, DRAM Read Burst,
DRAM Write Burst Timing, Fast MA to RAS# Delay CLK, Fast EDO Path
Select, Refresh RAS# Assertion, and ISA Bus Clock by different system
clock.
DRAM Timing
This item set the DRAM Read/Write timings that the system uses. When
item of "Auto Configuration" is disabled, this item will not show up.
DRAM RAS# Precharge Time
DRAM must continually be refreshed or it will lose its data. Normally,
DRAM is refreshed entirely as the result of a single request. This option
allows you to determine the number of CPU clocks allocated for Row
Address Strobe to accumulate its charge before the DRAM is refreshed. If
insufficient time is allowed, refresh may be incomplete and data lost.
This item sets the DRAM RAS Precharge Timing. The options are
4
and
3
CLKs.
DRAM R/W Leadoff Timing
This item sets the number of CPU clocks allowed before reads and writes
to DRAM are performed.
