BIOS modding?

I have been trying to get more out of my old Pentium CPU's in another post here I was told that the problems were that the mobo's that I am using don't allow for CPU voltage control and that how I was OCing it would also change the RAM speed and if the RAM was running to fast it wouldn't work, so I want to know if it is possible to mod the bios so that I can change the CPU voltage and overclock properly? The motherboards are  ASRock  G41M-VS3 R2.0's.

You can't.

@ShrimpBrimeThank you. Is there any way to learn how to edit the bios myself? I kind of think that it would be fun.

All the tools are in the first link I dropped here.

 

Bios modding can be very aggrevating. One wrong move, youll recover the board with a working bios. Can be a lot of back and forth.

 

Right now Im working on a bios mod for an HD 5670 and its Not going my way. 4 different modifications, and none of them work properly.  Im still researching this for my own amusement. Lol. Been at it 2 days now.....

Well increasing vcore. Increasing base clocks. Extending oc range. All result the card running 775 stock frequency. And driver level overclocking then stops working. 

 

 

What mobo are you doing it for? That’s the same thing that I need to do.

IMO yes. 

A board bios bricks, you no longer have a running system. A video card bios bricks, slap it in another slot, post with a different gpu and recover the bios.

 

 

Can’t you use the bios reset jumper? Or take out the CMOS battery?

For the mobo that I have there is a bios reset jumper and a cmos battery could I use those?

Those only reset the defaults of the bios. Removing the battery will also clear the time date. They do nothing for a bios flash in the way you think of it. Its more of a recovery tool from a bad setting.

 

To recover a bios on a motherboard is the same as flashing the bios. But you write a good known working bios, essentially recovering from a bad flash or messed up bios.

But how do you flash a new bios if the one in the board is bricked?
