INSTALLATIONS

Installing the Memory

The IB550F board supports one SODIMM DDR memory socket for a maximum total memory. The memory module capacities supported ar e 128MB, 256MB, 512MB and 1GB.

Installing and Removing Memory Modules

To install the DDR modules, locate the memory slot on the board and pe rform the following step s:

1. Hold the DDR module so that t he keys o f the DDR module align wit h

those on the memory slot. I nsert the module into t he sock et at a slight angle (approxim ately 30 degrees). Note that the socket and module are both keyed, which means that the module can be installed only in one direction.

2. To seat the memory module into the socket, apply firm and even

pressure to each end of the module until you feel it slip down into t he socket.

3. With the module properly seated in the socket, rotate the module

downward. Cont inue pressing downward until the clips at each end lock in to pos ition.

4. To remove the DDR mo dule, press the clips w ith both hands.

BIOS SETUP

BIOS Introduction

The Award BIOS (Basic Input/Output System) installed in your computer system’s ROM supports various processors. The BIOS provides critical low-level support for a standard device such as disk drives, serial ports and parallel ports. It also adds virus and password protection as well as speci al support for detailed fi ne-tuning of the chipset controlling the entire sys te m.

BIOS Setup

The Award BIOS provides a Setup utility program for specifying the system conf igurations and settings. The BIOS ROM of the system stor es the Setup utility. When you turn on the computer, the Award BIOS is im mediately activated. Pressin g the <Del> key immediately allows you to enter the Setup utility. If you are a little bit late pressing the <Del> key, POST (Po wer On Self Test) will continue with its test routines, thus preventing you from invoking the Setup. If you still wish to enter Setup, restart the system by pressing the ”Reset” button or simultaneously pressing the <Ctrl>, <Alt> and <Delete> keys. You can also restart by turning the system Off and back On again. The following message will appear on the screen:

Press <DEL> to Enter Setup

In general, you press the arrow keys to highli gh t items, <Enter> to select, the <PgUp> and <PgDn> keys to change entries, <F1> for help and <Esc> to quit.

When you enter the Set u p utility, the Main Menu screen will appear on the screen. The Main Menu allows you to select from various setup functions and exit choices.

Virus Warning

If this option is enabled, an alarm message will be displayed when trying to write on the boot sector or on the part ition table on the disk, which is typical of the virus.

CPU Internal Cache

Cache memory is additional memory that is much faster than conventional DRAM (system memory). CPUs from 486-type on up contain internal cache memory, and most, but not all, modern PCs have additional (external) cache memory. When the CPU re qu e sts d ata , th e system transfe rs the re qu e ste d data fro m the ma i n DR A M into cache memory, for even faster access by the CPU.

The WDT is used to generate a variety of output signals after a user programmable count. The WDT is suitable for use in the prevention of syste m lock-up, such as when software becomes trapped in a deadlock. Under these sort of circumstances, the timer will count to zero and the selected outputs will be driven. Under normal circumstance, the user will restart the WDT at regular intervals before the timer counts to zer o.
