The BIOS is the Input/Output System of the PC which will coordinate the start up when you start a pc.

Theres no BIOS within the mfc/dcp brother printers.

Need BIOS update for EliteGroup EF10MI Notebook

It may be that the BIOS battery has failed. if this happens the BIOS will lose all its settings and hence wont start up. Get someone who knows what they are doing to replace the battery and reset all the BIOS settings.

Bios locked

I can't find a decent manual for your laptop but there will be 2 pins on the motherboard that will say BIOS Clear. Short these 2 pins and turn the computer on. This is the only way to bypass the BIOS password. This operation will clear the BIOS and reset to factory defaults. After the BIOS is cleared, turn the computer off and take off the short.

Bios update failed.. Now all i get is 8 beeps and no display? Any solutions?

Hello,the only way to fix this problem is to prepare original bios file at your USB stick.But first you need to made this USB bootabile(put some universal BIOS fasher software from internet),than put the original file (bios)inside.when its finished try to find another PC (correct),pick up your BIOS chip,(the case of BIOS must be the same as another correct PC!!!!!!!!! IT IS VERY IMPORTANT),than turn on correct PC,run bios ,set USB stick as 1st bootabile device,save changes and restart PC,after that you will see universal Bios mask,you have choice to run bios file you already put on USB stick,DO NOT START FLASHING BIOS!!!!! PICK UP THIS BIOS CHIP FROM HIS CASE,THAN PUT YOUR BIOS CHIP (CHANGE CHIPS UNTIL THIS PC IS STILL WORKING)press enter and this PC will flash your BIOS with correct file.When its finished TURN OFF THIS PC(dont restart).Pick up your bios chip,and put it on your moterboard place for Bios,also put the bios chip from regular (correct)PC to its place,and you are finished.start PC you are using to fix problem ,just to check everything's OK,THAN TURN ON YOUR PC,IT MUST BE WORKING,9its look like risky job but dont worry its ok
I already fix lot of this problems,only check-dont short pins of chip,or turn chip at wrong direction,best luck :)

Download drivers

Ummm, no such thing.......

Driver: Small piece of software that allows the Operating System to communicate with a device

BIOS: Basic Input/Output System program

When you press the Power On button, the plastic assembly of the Power On button; presses against the Power On switch located inside it.

The Soft Power On circuit is activated.
This 'excites' the Power Supply, and turns it on.

The first chipset to receive power is the BIOS chipset.
The Basic Input/Output System program is initialized.

BIOS looks to see what devices are installed, does a Ram Memory count, turns the CPU (Processor) on; and hands the computer over to the Operating System.

To perform ANYTHING with BIOS in the respect you are stating, you would be performing a BIOS update.

The BIOS program in modern personal computers, no longer uses BIOS drivers.
"Older types of OS would use the BIOS to access hardware on the computer, but most new versions now access hardware directly through drivers built into the OS."

(OS = Operating System)

(Sometimes people just have to see another tech state this, just to make them feel comfortable about it, IMHO)

Know this;
IF, the power goes out when you are performing a BIOS update, your computer turns into an expensive doorstop.

IF, the BIOS update is not compatible with your computer, your computer turns into an expensive doorstop.

IF, you do NOT save the original BIOS program, and the above happens, your computer turns into an expensive doorstop.

Now,..........why is it you wish to fool with your BIOS program?
