    There was still a software BIOS on a ROM (flashable and it’s memory has always been dependant on a battery, to this day) back when you had to change settings with a jumper I’ve played with 286/386/486 systems then into Pentium 1’sEven super socket 7 used jumpers for FSB clocks and over clocking - All of these still had a BIoS

    Is UEFI an extention of BIOS, or does it work on them self without the bios?

  • Raoul Gerrits

    I have a problem, everytime i restart my pc i get to blue screen If i do not hit F11 so i get get to pop up window to choose which disk i want to start with and for this i need a ps/2 connection keyboard since a USB keyboard won't work and a few days ago my ps/2 port on my PC broke down and now i can't restart my PC since i'll get to blue screen if i do. I've read that i can activate the USB ports in the BIOS.. oonly i have to restart my PC to do this, iu'm very depending on my PC so i'm a bit scared to say the least. Is there a way to get into BIOS settings and activate the USB keyboard connection to "Enable" without restarting my PC?

    You don't need a bios, just rip it out

  • FallenPasha

    BIOS isn't hardware and software combined, it's software. As you called it, firmware, which is basically software on a chip.

  • Scott WIGLEY

    Are you aware of a good "trusted" utility to backup and restore bios settings ?

    Not going to lie, I only disliked this video because at the end he told me to suck it if I didn't like the video. Guy deserves success because he puts out great content, but I don't have to like your video because you told me to suck it otherwise. Enjoy!

    BIOS is not a fusion. It's software, pure and simple. It's actually an API. In reality there is no such thing as software. It's only a software from a human POV. The same way a book is just paper with ink on it. It's the human understanding of it, that makes it information.
