CHAPTER 3

Auto Configuration

Choosing Enabled (default) will automatically configure chipset

features using default settings. Choose Disable to customize setup.

DRAM Timing

Sets the DRAM speed at 70ns (default) or 60ns. It will set the

speed of the EDO/FP DRAM.

To be able to change the setting, Auto configuration must be

disable. If the Bus Clock is 75MHz, set it to 11/7/4. If the Bus Clock is 66/60/

55 MHz, set it to 10/6/4. Default setting is 10/6/4.

DRAM Read Burst (EDO/FP)

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

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

which sets the Read Burst time for accessing the DRAM. The timing used

depends on the type of DRAM and access time being used. The settings are

x222/x333, x333/x444, or x444/x444.

Note: If the user sets DRAM Read Burst (EDO/FP) as: x333/x444 it signifies

that:

a. 60ns EDO with 75 MHz Bus Clock is set at x333. If the Bus Clock is

66/60/55 MHz, then it is set at x222.

b. 60ns FP with 75 MHz is set at x444. If the Bus Clock is 66/60/55,

then it is set at x333.

c. 70ns EDO and FP DRAM, the burst time must be increased. So you

must set x222 to x333 and x333 to x444.

This option chooses the Write Burst Timing for accessing DRAM.

See: DRAM Read Burst Option. Choose x222/x333/x444.
