Question Help in building BIOS

[QweeilyNorth]

HP Pavilion dv6-6070se

I want to make a BIOS for this laptop that disconnects the external card and relies on the internal card because of a problem that occurred with the external card which made the laptop not work and now I want a BIOS maker to disconnect the card for the purpose of relying on the internal card

External card model is AMD Radeon HD 6770M

Internal card model is intel graphics hd 3000

The latest version of the original BIOS is

"Building" a custom BIOS/UEFI for a non-working laptop won't get you anything if you can't USE the laptop because of dead graphics. You'll still have to install that "built" BIOS/UEFI but you can't do that with the external graphics system DEAD and no way to download or install the new BIOS. So the real solution depends on what you can or cannot do with the laptop in it's current state. If you are LUCKY, you may be able to invoke the original HP UEFI/BIOS by starting the computer and holding down some key on the keyboard... sometimes it is F2, sometimes F12, sometimes some other key (user info for your laptop will say what key causes the laptop to go into BIOS/UEFI mode during a startup). The laptop should open with Intel Graphics as it won't have loaded the external graphics drivers when the BIOS/UEFI menu appears. In the BIOS/UEFI menu you will find a setting for graphics that lets you specify Intel Graphics. Do that, save the changes to the BIOS, the computer should restart. Run System Information to confirm you are using Intel Graphics. If that is correct, you can delete everything associated with the external graphics. For that matter, you MIGHT be able to invoke Intel Graphics just by disconnecting the external graphics. When the laptop cannot find the external graphics, it might revert automatically to Intel Graphics. Lots of "ifs" and "mights" in there--you'll have to sift through them. But I don't think you need a custom built BIOS/UEFI. Even if you have that now, you can simply go to the HP website and download official HP UEFI/BIOS for your laptop's serial number and Intel Graphics will be used by default when the computer restarts with the original HP BIOS/UEFI installed.
