Bios Mods -The Best BIOS Update and Modification Source

Hello everyone!
This is the first time I post on this forum.
Let me explain my problem:
This morning I wanted to disable the Intel chipset to operate only 630m chipset (Nvidia Optimus).
Previously I had installed the modified bios.
But huge mistake on my part, the PC will not start, a black screen ...
I tried to remove the battery on the motherboard, to shunt jumper beside the ram ... No change.
I tried reinstalling the Bios (v2.28) on a USB stick and flash with the Fn + Esc ... No change.
Help me please ...
Sorry for my English, I used Google translation from French to English

So Bricked !
Buy the Tools and I will help You to make this job !

Hi. Thank you for your response.
I resolved my problem : I put off my battery CR2032 during 30 minutes (first time only few secondes)
After, I used a USB key in FAT32 with your modded bios to flash in emergency same as the first time with FN + Esc.
Flashing succesful.
Thank you a lot with your website

many thanks for your compliments !
