When you installing AGP card, please make sure the following
notice is fully understood and practiced. If your AGP card has
"AGP 4X/8X(1.5V) notch"(show below), please make sure your AGP
card is AGP 4X/8X(1.5V).
AGP 4X/8X notch
Caution: AGP 2X(3.3V) card is not supported by VIA
KT400A. You
®
might experience system unable to boot up normally. Please insert
an AGP 4X/8X(1.5V) card
Example 1: Diamond Vipper V770 golden finger is compatible with
2X/4X mode AGP slot. It can be switched between AGP 2X(3.3V) or 4X
(1.5V) mode by adjusting the jumper. The factory default for this card is
2X(3.3V).
The GA-7VAX-A / GA-7VAX1394-A / GA-7VAXP-A / GA-7VAXP-A Ultra
motherboards might not function properly, if you install this card without
switching the jumper to 4X(1.5V) mode in it.
Example 2: Some ATi Rage 128 Pro graphics cards made by "Power
Color", the graphics card manufacturer & some SiS 305 cards, their
golden finger is compatible with 2X(3.3V)/4X(1.5V) mode AGP slot, but
they support 2X(3.3V) only.
The GA-7VAX-A / GA-7VAX1394-A / GA-7VAXP-A / GA-7VAXP-A Ultra
motherboards might not function properly, If you install this card in it.
Note : Although Gigabyte's AG32S(G) graphics card is based on
ATi Rage 128 Pro chip, the design of AG32S(G) is compliance
with AGP 4X(1.5V) specification. Therefore, AG32S (G)will work
fine w ith VIA
KT400A based motherboards.
®
Before you install PCI cards, please remove the Dual BIOS
label from PCI slots if there is one.

  • Page 76 STEP 6: Load BIOS defaults. Normally the system redetects all devices after BIOS has been upgraded. Therefore, we highly recommend reloading the BIOS defaults after BIOS 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. The boot up screen will indicate your motherboard model and current BIOS version.

The concept of this technology is based on the redundancy and fault tolerance theory. DualBIOS simply means there are two system BIOSes (ROM) integrated onto the motherboard. One is a main BIOS, and the other is a backup BIOS.

It protects your BIOS during system POST, ESCD update, and even all the way to PNP detection/assignment. DualBIOS provides automatic recovery for the BIOS. When the first BIOS used during boot up does not complete or if a BIOS checksum error occurs, boot-up is still possible.

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 BIOS checksums when booting-up.
