Page 19: Step 2: Install Memory Modules
Step 2: Install memory modules The motherboard has 3 dual inline memory module(DIMM) sockets. The BIOS will automatically detects memory type and size. To install the memory module, just push it vertically into the DIMM Slot. The DIMM module can only fit in one direction due to the notch. Memory size can vary between sockets.

Please flash the BIOS according to the following procedures if you are now under the DOS mode. Flash BIOS Procedure: STEP 1: (1) Please make sure your system has installed the extraction utility such as winzip or pkunzip. Firstly you hav e to install the ex traction utility such as winzip or pkunzip for unzip the files.

Page 70 (3) It will pop up a screen and asks "Are you sure to flash the BIO S?" Press [ Enter] to continue theprocedure, or press [ESC] to quit. Beware: Please do not turn off the system while you are upgrading BI OS. It will render your BIOS corrupted and system totally inoperative.
Page 71 STEP 6: Load BIOS defaults. Normally the system redetects all devices after BIO S has been upgraded. Therefore, we highly recommend reloading the BIO S defaults after B IOS has been upgraded. This important step resets everything after the flash. (1) Take out the floppy diskette from floppy drive, and then restart the system.
Page 72 (3) Use the arrows to highlight the item "SAVE & EXIT SETUP" and press "Enter". System will ask "SAVE to CMOS and EXIT (Y/N)?" Press "Y" and "Enter" keys to confirm. Now the system will reboot automatically, the new BIO S setting will be taken effect next boot-up. AMIBI O S SIMPLE SETUP UTILITY - VERSION 1.24b (C) 2001 Ameri c an Megatrends, Inc.

What’ s DualBIOS On GIGABYTE motherboards w6ith DualBIOS there are physically two BI OS chips. For simplicity we’ ll call one your “Main BIOS” and the other we’ ll call your “Backup” BIOS (your “hot spare”).
Page 77 I. Q: What is DualBIOS technology? Answer: DualBIOS technology is a patented technology from Giga-Byte Technology. The concept of this technology is based on the redundancy and fault tolerance theory. DualB IOS simply means there are two system BI OSes (RO M) integrated onto the motherboard. One is a main BIOS, and the other is a backup BIOS.
Page 78 III. Q: How does DualBIOS technology work? Answer: DualB IOS technology provides a wide range of protection during the boot up procedure. It protects your B IOS during system POST, ESCD update, and even all the way to PNP detection/assignment. DualBIOS provides automatic recovery for the BIOS.
Page 79 utility may be entered to manually change the boot sequence to boot from the backup BI OS. 2. During or after a BIOS upgrade, if DualBIOS detects that the main BIOS is corrupt, the backup BIOS will take over the boot-up process automatically. Moreover, it will verify the main and backup B IOS checksums when booting-up.
