I have a Samsung 960 EVO NVMe M.2 SSD that appears as an external drive (orange disk icon) in High Sierra (10.13.6). The SSD is in an M.2 to PCIe x4 adapter on Gigabyte GA-Z87X-OC Force motherboard. The board does not natively support NVMe boot but I modded the BIOS.
I have attempted to follow Pike's guide from https://pikeralpha.wordpress.com/2016/07/01/help-my-nvme-show-up-as-external/ but I have an issue. This motherboard has a PCIe bridge (only way to have so many PCIe lanes on a consumer, non Xeon chipset). I have followed the Pike guide with success on a different build, but that board doesn't have any weird PCIe bridges or other non-standard issues.
My goal is to (1) improve performance and (2) fix the drive icons and macOS thinking the drive can be ejected.
I have attempted to use PEG0 in the SSDT patch but to no avail. I am stumped what else to try.
Drive performance is well below expectations.
Attached is a full IORegistryExplorer dump and my Clover directory (serial numbers removed). Any help or thoughts at all is appreciated. Thank you!
