Hello !

I've recently bought an Lenovo Y50 70P touch, (9ECN43WW V3.03) and i've try to unlock the bios, i've dumped it but it's not an apito 4 like my old msi, so i'm totaly newbie with Insyde bios , i just wanna unlock all option about power configuration and overclocking feature, downgrade the microcode to 00 (allow overclock), i know what i'm doing and i've a spi programmer if somethings turn bad.

Here is the dump of my bios, i've look for the bin file on the web but i can just found an exe flash file from the lenovo support site.

Thanks for your help !

Note : This laptop have a 4720HQ, like my old msi, i'm wondering how far i can push it (4.4Ghz @ 8 core 1.3v )

Note 2 : I was only able to read 1 chip with my spi programmer, i don't know why.
