Bios Mods -The Best BIOS Update and Modification Source

Hi all!! I need to unlock advanced setting on this bios becouse i HAVE TO "ERASE" my discrete video card and use only the intel HD one (i suppose the ati one has some hardware problems...).

This is the link to the hp bios:
sp55430

I've downloaded and installed the unlocked bios in the repository posted by camiloml
sp55430_UlkMenus_ByCamiloml
but unfortunally it doesn't work ,
when i go to the advanced tab -> Video Configuration i can switch between:
[>Hybrid, iVGA, dVGA]
but if i select >iVGA at reboot my screen stay black and no HP logo is shown, so i've restored the original bios.

I hope you can fix it, i really need to have this unlocked bios...

Motherboard: HP 143A
Bios: InsydeH20 ref3.5 f.48
PC: HP G62 b07sl

No not moddable just same issues for all Manufacurers Bioses !
Regards

Hybrid = can choice between Dedicated (Discrete) or Internal (CHIP)

iVGA = Internal = CHIP

dVGA = Discrete = PCI Card on Slot

May be your laptop has not the twice Graphic Card (It's the most exansive) !

I have 2 graphic cards:
- Integrated Intel HD
- Discrete ATI Mobility Radeon 5470
I need to disable the Discrete one

UPDATE:
I've downloaded this version uploaded by the user gabiz_ro:
gabiz_ro_sp55430
This time if i select >iVGA the pc boot normally (no bricks), but when i open the bios setup i see that the setting has been automatically restored to >Hybrid
Same issue if i select >dVGA, he always go back to >Hybrid.
Why???

Thanks in advance guys
