Bios Mods -The Best BIOS Update and Modification Source

In fact the bios is stored in the chip ? or is stored somewhere else ? Can you tell me?

I can belive i made it ). I have replaced the bios chip from an old motherboard that i had same board for HP g72 and the laptop successfully started. Thank you everyone !

I relied in PM said that the MoBos are the same !
Reagrds

I saw thank you BDMaster now i have another problem I have two GPU's one is Intel HD 1st Generation and one is ATI Mobility Radeon HD 5470 now the windows sees with this bios that i have only one GPU which is ATI. Do you have any suggestion for this?

Yes It seems your HW preserve the Muxeless solution so You will see Always one Card !

The bios that i had before showed up two Graphic cards in Device Manager, Intel GPu and ATI Gpu now with this bios chip that i have changed from that old MoBo it's showing only ATI, then that means Intel GPU is useless
But anyway i don't need Intel i just wanted to know why with this chip i see only one, and why with that bricked chip i saw two gpus. For my knowledge

I think EC rom version isn't match with BIOS version.
That happens once to me.

(Was my mistake,tired to disassembly-assembly laptop to reprogram BIOS chip when bricked,I remember that on schematics I see one connector for external SPI chip.Add connector to motherboard,was under wifi card,get wires from connector to programmer,all was fine but software see other id of SPI chip,Ignored this,maybe my memories are wrong,write bios to chip,with some errors.Result laptop completly dead.
WTF I do wrong?Check some things,other thing all seems fine but laptop dead.Until looking in schematic I see some differencies from what I remember,check again and see the problem.Almost similar schematic,same connector for external SPI chip etc.
This one was for main chip,BIOS,the other one was for EC SPI chip.Find on net dump of that chip,write with programmer.Laptop alive)

Sorry for long post but was to explain my mistake,confusion of two sockets.
Maybe will be useful for someone sometime.

After that I only get one video card,ATI in dev manager.
Intel one was non existent.
After writing BIOS,sp55430,all was fine and both vide cards available.

To help the owners of HP G72 to detect where is the BIOS CHIP location if they don't have schematics of it here is a picture that i have on my own motherboard.
BDMaster you could make a thread inside this forum with types of laptops and BIOS CHIP locations that would be easy for everyone to find their own bios chip without schematics, because not everyone has access to schematics ^^


Here is the bios location:
