Hardware Questions

What is the difference between version 5.0 and version 2.0 of the motherboard?

Version 5.0 adds support for Intel Tualatin (Pentium III 1.0GHz and higher; Celeron 1.2GHz and higher) based CPUs.

What is the difference between version 1.0 and version 2.0 of the motherboard?

Version 2.0 adds support for ATA-100 IDE HDDs.

How do I enable or disable the onboard audio?

Go into the BIOS setup, and then to Integrated Peripherals. Enable or disable the Onboard AC'97 audio option. Click here for the audio drivers.

How do I enable or disable the AMR modem slot?

Go into the BIOS setup, and then to Integrated Peripherals. Enable or disable the Onboard MC'97 modem option.

How do I enable ATA-66 IDE support?

You need an IDE HDD that is ATA-66 compliant. In addition, make sure the IDE cable (40 pin, 80 conduct) you're using is also ATA-66 compliant.

My HDD is not ATA-66, can I still use it?

Yes, the onboard IDE controller is downwardly compatible with PIO, DMA, or ATA-33 HDDs.

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 or Windows 2000 comes with native USB drivers.

What kind of DIMMs should I use?

The motherboard only accepts PC100/133, unbuffered, 3.3V SDRAM DIMM (ECC or non-ECC) ONLY!

Do I need to use PC133 SDRAM DIMM?

Yes, if your processor is running with a 133MHz CPU host bus, then you must use PC133 rated SDRAM DIMM.

Can I use just one DIMM?

Yes.

What is the system's maximum memory capacity?

It is 1.5GB using three registered 512MB DIMMs.

Does the system support ECC memory?

Yes. To enable ECC support, go into the BIOS. Go to CHIPSET FEATURES SETUP, and change "DRAM Data Integrity Mode" to ECC. Note, this option is only available if you've installed ECC DIMM.

Operating System Specific Questions

I have an Unknown Device in Device Manager under Windows 9x or W2K.

If you do not have an AMR modem installed, then make sure the Onboard MC'97 modem option is DISABLED in the BIOS.

I have an Unknown PCI Multimedia Device in Device Manager under Windows 9x or W2K.

Most likely this is caused by onboard VIA AC97 sound. If you are using an add-on soundcard, then make sure the Onboard AC'97 audio option is DISABLED in the BIOS. If wish to use the onboard audio, then make sure you have the drivers loaded.

Do you have a troubleshooting guide for Windows 98/98SE?

Yes, we do; please see Premio Windows 98/98SE Troubleshooting Guide.

Do you have a troubleshooting guide for Windows 2000?

Yes, we do; please see Premio Windows 2000 Troubleshooting Guide.

I have the V94S version 2.0 and am having trouble installing Windows 2000 SP1 onto a Western Digital ATA-100 HDD.

Follow these steps to install W2K to a WD ATA-100 HDD. 

1. Download the WD UDMA utility (174K) and extract the file to a bootable floppy disk.

2. Boot from the floppy disk and run DLGUDMA.EXE and follow the onscreen instructions to change the HDD mode from ATA-100 to ATA-66.

3. Install W2K normally.

4. Download the VIA W2K IDE driver (1MB) and extract it and run SETUP.EXE. (Note, it may take two reboots to complete the installation.)

5. Boot from the floppy and run DLGUDMA.EXE and change the HDD mode back to ATA-100.

Processor Settings
There are no physical jumpers or DIP switches to set for the processor speed; it is set in the BIOS under Hardware Monitor Setup.

To get into the BIOS, keep hitting the DELETE key during the memory count screen. Then go into the Hardware Monitor Setup. For most processors, the system will auto detect your processor type and speed and set itself accordingly.

If you wish, you can manually set the CPU Host Clock (MHz) and CPU Ratio Selection; please refer to the table below.

If you set the CPU Host Clock (MHz) or CPU Ratio Selection too high, then you must clear the CMOS first, so you can get back into the BIOS.

Processor	CPU Host Clock (MHz)	CPU Ratio Selection
Intel Pentium III/500E	100	5.0x
Intel Pentium III/550E	100	5.5x
Intel Pentium III/600E	100	6.0x
Intel Pentium III/650	100	6.5x
Intel Pentium III/700	100	7.0x
Intel Pentium III/750	100	7.5x
Intel Pentium III/800	100	8.0x
Intel Pentium III/850	100	Autodetect by BIOS
Intel Pentium III/533	133	4.0x
Intel Pentium III/600EB	133	4.5x
Intel Pentium III/667	133	5.0x
Intel Pentium III/733	133	5.5x
Intel Pentium III/800B	133	6.0x
Intel Pentium III/866	133	6.5x
Intel Pentium III/933	133	7.0x
Intel Pentium III/1,000	133	7.5x

Note that the E designation means it is a "Coppermine" CPU, while the B designation means the CPU host clock is 133MHz. Also, if the CPU Host Clock (MHz) is set to 133MHz then PC133 SDRAM DIMM is required.

Front Panel Connector Block (JFP1)

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

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.

Diagnostic LEDs (D-LED)

D-LED may not be available on version 2.0 of the system board. The row of diagnostic LED at the rear of the system board allows you to determine the cause of a problem. If the D-LED stops at a certain state, then refer to the table below for the probable cause and solution, if any. Note the LEDs are labeled 2, 3, 4, and 5, with LED 5 being the topmost one.

D-LED	Description	Cause/Solution
	System power on; begin BIOS initialization	Processor not setup correctly or damaged; possible bad onboard battery/Replace CPU and/or battery
	Chipset initialization	Possible damaged chipset/Replace system board
	Memory detection test; testing onboard memory size	Memory not installed correctly or bad memory module/Check or replace memory
	Decompressing BIOS for fast boot	Possible damanged BIOS chip/Replace or reflash BIOS
	Initializing keyboard controller	Bad keyboard or controller/Replace keyboard or system board
	Testing shadow RAM; read/write shadow RAM area	N/A
	CPU initialization; display CPU type, bus type, etc.	N/A
