How to update BIOS?

tidusmaximus1 · Aug 16, 2014

I have a situation. I have a new processor and a new mother board. the mobo is older and only supports the processor after a BIOS update. How do I update the BIOS in this situation?

BIOS updates need a working system. The BIOS can be updated via Windows or Dos (check MB producer website for more instructions). So, basically you need a working CPU to startup your system.

Can I download the update to a usb and update in the BIOS?

It depends on the motherboard you have, so what motherboard do you have?

tidusmaximus1 :

It still needs a working CPU to upgrade the BIOS.

Not necessarily, some motherboards can be updated without a CPU.

@tidusmaximus1 No, you can't update your z87-A motherboard without a CPU. It doesn't support usb bios flashback. But the motherboard might very well come to you with an updated bios.

thank you

tidusmaximus1 · Aug 16, 2014

But please one more thing. If i test to see if i have the update by inserting the cpu, does that risk anything braking?

You're welcome.
And no, but you should no what bios version it is before opening the box anyway, there's a sticker on the box that tells you what bios version is loaded on it. If it has the bios version 2004 or higher on it, you should be fine.
