CHAPTER 3

Fast EDO Lead Off

Under Auto config., the BIOS will identify which type of DRAM is

being used. Choose the setting accordingly. To customize, use this option.

Choose Enable or Disable. If the system is using EDO DRAM, choose

enable. But if the system is using both EDO and FP DRAM, choose Disable.

Refresh RAS# Assertion

The settings are 4 Clks or 5 Clks. Using 60 ns DRAM at 75 Mhz Bus

Clock must be set to 5 Clks, while 66/60/55 Mhz Bus Clock must be set to 4

Clks. But if you use 70 ns DRAM, it must be set to 5 Clks.

Fast RAS to CAS Delay

The settings are 2 or 3. 2 RAS to CAS delay is set to 2 clock, while

3 RAS to CAS delay is set to 3 clock. The clock is dependent with the

DRAM Timing and Bus Clock.

DRAM Page IDLE Timer

The settings are 2 Clks, 4 Clks, 6Clks, or 8 Clks. Default setting is 2

Clks.

DRAM Enhanced Paging

Choose Enable(default) or Disable.

Fast MA to RAS# Delay

The settings are 1 Clks or 2 Clks(default). During 1T, one bus clock

is allowed, while 2T allows two bus clock for MA address setup time to

RAS assertion. This is also dependent on DRAM Timing.

SDRAM (CAS Lat/RAS-to-CAS)

The settings are 3/3 or 2/2. This option is for SDRAM CAS latency

time and RAS# to CAS# delay time. The default setting is 3/3.
