    I build a new pc I'm stuck with as bios?I what comes 1st? Bios setting or Windows software installation?

  • David Grisez

    If you go far back in computer history to the 1960's computers did not even have a bios. The computers back then required set of machine language code on punch cards read by a card reader to get the computer operating.

  • Immortal Axolotl

    Nice UEFI propoganda. It’s a shame you don’t need UEFI for GPT though, otherwise UEFI would be legitimate.

  • Jommer De Luna

    I wish the 8 beep error on the Alienware M17x R3 was this simple.

  • Jake Higginbotham

  • The Laptop Lagger

    I prefer the bios user interface over that of UEFI but that's only because I've seen some spectacularly shit UEFI interfaces while the more basic BIOS interface (no mouse support no nothing) never failed me

  • Ridley On Steroids

    So, what about GPU's? How are they affected by this? Is newer bios required to run newer GPU's?

    I really like how you are trying to sell the analogy of the brain stem being the BIOS of a human.
