3486 motherboards are in the 486 section.

We strongly advise against changing your motherboard's BIOS unless you have a specific need to do so.


A mistake made in changing the BIOS could result in your system becoming dead -- No video, no beeps, nothing. Repair in this situation usually involves replacing the BIOS chip. This is not covered under warranty, and may require sending your motherboard in to be serviced at a cost to you.

Please e-mail support@dfiusa.com if you have any questions about BIOS upgrades, before flashing the BIOS.
