    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.

    I'm running Windows 9x and plug & play doesn't seem to work.

  • Go into the BIOS's PCI/PnP Configuration and enable the PnP OS option.

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

  • Power off your system, move JBAT1 to 2-3 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'm have a Celeron/366 or 400, what's the correct jumper settings?

  • The Celeron/366 or 400's clock multiplier is locked.
  • Which means it does not matter what your jumper settings are; the BIOS will autodetect and run the processor at the correct speed.

    What is the difference between the Intel Celeron/300 and Celeron/300A?

  • The 300A or 333A processor comes with 128K L2 cache.

    How do I disable the onboard Yamaha YMF740 PCI sound?

  • Go into the BIOS / Integrated Peripherals, and disable the onboard sound.

    Can I upgrade to more than 8MB SDRAM video memory?

  • No, the EX2's video memory is fixed at 8MB SDRAM.

    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 comes with native USB drivers.
  • Windows 95 (version 950B/950C only!) can enable the USB ports by getting the Microsoft USB driver and Intel USB INF update.

    Can I use just one DIMM?

  • Yes, the system board will work with just one DIMM present.

    What is the EX2's maximum memory capacity?

  • It is 256MB (two 128MB DIMMs).

    What kind of DIMMs should I use?

  • The PREMIO EX2 motherboard only accepts unbuffered, tin leads, 3.3V SDRAM DIMM ONLY! You can use either 66MHz or PC100 DIMM.

    I have a PnP soundcard and PnP modem, but I'm getting conflicts.

  • It's recommended that you let the modem take COM2 (2F8h/IRQ3); see the question below.
  • And set the soundcard at 220h/IRQ5/DMA1, if possible.
  • Also, try adding the card in one at all time; put the soundcard in first, let 95 detect it, then add the modem.

    I have a plug and play modem, how do I setup it for COM2 in Windows 95?

  • Disable serial port 2 in the BIOS and remove the COM2 port, if present, in Windows 95's Device Manager.

    The JP1 jumper block is located between the onboard IDE connectors and the battery. The jumper next to the IDE connector is 1; the one closest to the battery is 4. (Refer to System Board Diagram above.)

    Front Panel Connector Block (JFP1)
    PREMIO EX2 Front Panel Connector Block
    For the keyboard lock jumper, putting a jumper on it will lock the keyboard; so it should be open by default. If the HDD LED, power LED, or speaker doesn't work, try reversing the connector.

    Back I/O Connectors
    PREMIO EX2 Back I/O Connectors
    Don't mix up the PS/2 mouse and keyboard connector, otherwise your keyboard may not work properly. It's highly recommended that you use powered speakers for the onboard sound. The joystick port is also the MIDI port.
