Hi all, I have a Alienware Laptop here (Haswell HM87) and got my hands on RTX A4500 MXM GPU. It doesn’t post and I am told it’s because GPU requires above 4g decoding/resizable bar.
I found the resizable bar thread by @Kuri0 and from what I can see, I can add the DXE to the BIOS right under the NVMe DXE in BIOS (I think I am doing this part correctly) using UEFITool.
The problem is, my unlocked bios doesn’t seem to have the option above 4g decoding. This part I tried looking up and can’t figure out how to add/check. Can someone help me with my bios for above 4g decoding?
Thank You
