[Request] Unlocking Bios toshiba qosmio x775

[ahmedjb]

Greetings,
I have a Toshiba Qosmio x775-Q7380 with vbios v2.1 and the laptop gpu Nvidia gtx 560M (cpu intel i5 2430M sandy bridge) is starting to not be enough to run some games (Mafia 3). I saw that my laptop has a mxm 3.0-b slot and I was thinking of replacing my mxm 3.0-b gtx 560M with a mxm 3.0b gtx 770M from the qosmio x70-a. Also the power supply is basically the same from both cards. I feel like its gonna come make issues with the bios of my laptop not wanting to accept the graphics card. Can anyone help me out understand more regarding this? I'll attach a link/file of my bios in order for it to be unlocked.

I tried putting a gtx 770m from toshiba qosmio x70-a inside my qosmio x775 and the laptop would just keep rebooting (the logo comes on then the laptop reboots then again and again). I thought the gtx 770m from another toshiba laptop would work on my toshiba. but I think this has to do with the bios. I feel like I have to modify the bios then at least the laptop would boot into windows instead of just keep restarting on logo screen. I'm new to this sort of stuff, but I'm willing to take a chance.
