How Do I Perform A FLASH BIOS Procedure?

Different BIOS versions will require different reflashing methods and software. Download the appropriate BIOS file and follow the instructions. Note: some BIOS changes can’t be FLASHED if the revision changes are major, and a BIOS chip replacement may be necessary. Contact us for your specific requirements.

Why Doesn’t The PS/2 Mouse Port Work?

During hookup make sure that you are installing your PS/2 mouse with your system powered off, otherwise you could permanently damage the motherboard.

How To Identify a Corvalent Motherboard?

All of our products have a PID label that includes motherboard part number, serial number and date code.

Example: FI-P45MX-01/6 0701-33066
Featured Item = FI Motherboard
Part# = P45MX
Configuration Type = 01
Motherboard Revision = /6
Serial Number = 0701-33066. The 0701 indicate the datecode of the board

It is very important to have this information in hand while asking for technical support.

When I Power Up My Motherboard, I Get No Display, No Beep And No Post Codes Changes. What Happened?

This condition may imply that the CPU is not able to run any instruction. Please check for a bad CPU, improper inserting of CPU at the socket, wrong jumper settings around the CPU type and voltage or even the DC power cables from the power supply to the motherboard. For all the P4 motherboards, make sure to have the proper ATX12V power supply and to connect the additional 12V power supply connector.

I Have 128 MB Of Memory Installed; Yet MS-DOS Only Reports 64 MB. What Is Wrong?

16-bit Operating Systems such as MS-DOS cannot access greater than 64 MB of memory. 32-bit Operating Systems will report the correct memory installed above the MS-DOS 64 MB memory barrier.

How Can I Ensure That I Have The Best Setting In My BIOS?

The BIOS optimal default settings are constantly reviewed for performance and compatibility.

Can I Mix Different Brands, Speeds And Types Of Memory On My Motherboards?

Mixing memory may introduce timing and other electrical issues that can affect system performance and reliability. Check with your board’s manual for correct memory types.
