Hello. I need help with a BIOS mod for my Toshiba Satellite L850.

- Board model: DK10FG
- PCB part number: 6050A2491301-MB-A03
- BIOS chip: Winbond 25Q64 (8MB)
- Original GPU: AMD Radeon — already physically removed
- Symptoms: Board powers on (fan, LED, Caps Lock working), but no display via internal screen or VGA.
- I confirmed the short was on the AMD GPU and it's now removed.
- I suspect BIOS is still locked to PEG (discrete GPU), and does not fallback to Intel iGPU.

Please help me modify the BIOS to:

1. Force `Primary...
