How do I edit nvidia bios

[kraelic]

I have a 965m that I would like to edit just the vendor ID so that the nvidia drivers just install without test signing hoops.

PCI\VEN_10DE&DEV_1427&SUBSYS_05AA1028&REV_A1
PCI\VEN_10DE&DEV_1427&SUBSYS_05AA1028

I copied the bios with GPU-Z, but Nibitor cannot recognize it. I am seeking to change 05AA to 0707 for my alienware.

As far as I know you cannot change the vender ID since it's embedded on the PCB somewhere. You can change the speed and manufacture but the VEN ID never changes.

You can't, that breaks your warranty and is likely illegal.

Well my warranty is already expired. I decided to open the .rom in a hex editor and I can find the Vendor ID and Device ID in two locations, DE 10 27 14, but I do not want to change those. The subsystem however I cannot find together, but I find 3 instances of AA 05 and one instance of 28 10.

10DE is nvidia, 1427 is the 965m, 1028 is dell, the last part in the drivers is 0707, but the card needs that altered to 05AA in the nvdmi.inf 05AA is all over the 700m and 800m options though. I am beginning to wonder if it has something to do with the laptop bios at this point. like my alienware chassis is 05AA 1028 and the newer model with the 965m soldered on are the 0707 1028 chassis.

If it was that easy people would change Geforce to Quadros all the time. Years ago nvidia locked the VEN ID in the PCB. You can change it in the bios all you want but the drivers are going to still see the original ID.

It is the subsystem I want to change, vendor ID and device ID are fine at stock I misspoke in the OP. The subsystem is keeping the drivers from just installing. I have to mod the drivers and change the subsystem from nvidia's expected 07071028 to 05AA1028 in two spots and 1427.0707.1028 to 1427.05AA.1028 in 3 spots in the nvdmi.inf which kills the driver signature, then disable the driver signatures and install then leave test mode. If I could just have the card match the expected subsystem I would not need to jump through the hoops to install the drivers.

What I need now is a bios dump from an alienware with a 965m built in for hex comparison.
