Memory Configurations

In this section, the UM4981 AI0 DRAM and cache configurations are discussed. Users are recommended to read through this section before installing or removing memory.

2.1 System Memory

The UM4981 AI0 DRAM provides tremendous flexibility to support a number of

different on-board DRAM configurations. The on-board DRAM is installed with SIMM (Single-In-Line Memory Module). There are four memory banks capable of supporting

The following table lists all the possible DRAM module combinations and the total memory amount for each option.

Boot

Options

-

enables the system to perform seek on the floppy drives before booting. And determines the sequence with which the system will proceed when booting the operating system.

Security

-

provides special access for the user to enter the operating system

and Setup program, and restricts unauthorized access to the floppy disk drives.

Green PC Features

-

allows the timer settings for the DOZE, STANDBY and SUSPEND modes. It also lists the SMI events by which the system wakes up from STANDBY or SUSPEND modes. If the device is not active, Power Management Function will slow down the CPU speed and both IDE and monitor will be put into doze, standby, or suspend mode.

Load ROM Default Values

-

allows for automatic configuration of all the

above options using the default values of BIOS.

Load Values from CMOS

-

allows for automatic configuration of all

the

above options using the previous values saved in the CMOS SRAM.

Save Values to CMOS

-

saves the changes you have made in the Setup pro-

gram, then quits and reboots the system.

To choose an item from the Setup main menu, move the cursor to appropriate line using the Up < ?’ > and
