Hi,

I got a Lenovo Thinkcentre M75n (MT-M 11G5 PF3XG5V3) with a semi-bricked bios.

Short recap: I want to add an external GPU via the M.2 slot (Oculink). It does work but has some problems with the onboard GPU of the Ryzen 3 3300U. So I used Smokeless_UMAF to disable it. Since then I don't get any video via the external GPU nor the iGPU and Can't access the BIOS, but the PC does boot to the OS.

I desoldered the flash IC MX25U12872F and dumped the flash.

I also downloaded the newest BIOS and have it as a .bin file (I loosely compared the contents...

Hey there, working on PCs to build micro sized gaming machines. For my current build (a Lenovo M75 Nano) I need some BIOS Help here.
