    BIOS Questions

    How do I get into the BIOS setup?

    Keep hitting the DELETE key during the system memory count.

     

    Do you have a BIOS history file that includes the problem(s) fixed for each revision of the BIOS?

    Yes, click here for the file.

     

    How do I update or flash my BIOS?

    Updated BIOS are available on our FTP site.

     

    How do I clear the CMOS? How do I clear the BIOS password?

    Power off your system and move JBAT1 (see system board diagram) to 2-3 (towards the edge of the motherboard) and leave it there for 2 or 3 seconds. Move JBAT1 back to 1-2 and power up your system.

     

    I have flashed my BIOS, but now I get no video!

    Try clearing your CMOS (see above). Make sure you've flashed the BIOS using the correct BIOS for your system board; flashing the wrong BIOS will render the board inoperable.

    Hardware Questions

    I have 128MB of system memory, but it is showing only 96MB.

    If you are using the onboard SiS 651 video, it will take away a MINIMUM of 4MB from your system memory. For example, if you have 128MB of system memory, and you set the onboard video for 32MB, you will actually have a total of 96MB (128MB - 32MB = 96MB). The onboard video uses a shared video memory architecture. You can adjust the amount of video memory allocated in the BIOS (please see the question below).

     

    How do I adjust the amount of system memory allocated to the onboard video?

    Go into the BIOS setup (hit DELETE key while system is booting up) and go into Integrated Peripherals / System Share Memory Size. You can select 4, 8, 16, 32, or 64MB.

     

    How do I get the full amount of system memory?

    You need to add an AGP video card; that will automatically disable the onboard video and free up the system memory. 

     

    Can I use the onboard video AND an AGP video card simultaneously?

    No, adding an AGP video card will automatically disable the onboard video. 

     

    How do I disable the onboard video?

    Adding an AGP video card will disable the onboard video.

     

    How do I disable the onboard audio?

    Go into the BIOS setup (hit DELETE key while system is booting up) and go into Integrated Peripherals / SiS OnChip PCI Device / SIS AC97 AUDIO and set it to disabled.

     

    How do I disable the onboard network adapter?

    Go into the BIOS setup (hit DELETE key while system is booting up) and go into Integrated Peripherals. Set Onboard LAN device and Onboard LAN boot ROM to disabled.

     

    Why doesn't my AGP video card fit in the AGP slot?

    The system AGP slot is for AGP 4X, 1.5V compliant video cards only. Older AGP video cards will not fit because it does not operate at 1.5V. The only solution is to upgrade your existing AGP video card to one that is 4X and 1.5V compliant.

     

    I've turned the system on, but I'm getting no power (i.e., power supply fan does not spin).

    Make sure the cable from the case's power switch is connected properly to the board's power on jumper; refer to the motherboard manual. Try reseating the ATX power connector to the motherboard. Disconnect all the power connectors to your HDD, FDD, CD-ROM, etc. then try powering the system up. Try replacing the ATX power supply.

     

    I have two USB ports in the back, how do I enable them?

    Windows NT 4.0 currently do not support USB. Windows 98/98SE, Windows 2000, Windows Millennium Edition (Me), and Windows XP all come with native USB drivers.

     

    What kind of DDR DIMMs can I use?

    DDR266/2100 or DDR333/PC2700, non ECC DDR DIMMs.

     

    Can I use just one DIMM?

    Yes. 

       

    What is the system's maximum memory capacity?

    It is 1GB using two 512MB DIMMs.

    Processor Setting

    There are no jumpers or DIP switches to configure for the CPU speed. Just install the CPU and the BIOS will autodetect the proper speed and voltage settings.
