    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 DIMM sockets) 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

    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 / AC'97 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 Selection 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/PC2100, non ECC DDR DIMMs.

     

    Can I use just one DIMM?

    Yes. 

       

    What is the system's maximum memory capacity?

    It is 2.0GB using two 1GB DIMMs.
