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 email@example.com if you have any questions
about BIOS upgrades, before flashing the BIOS.
