I just noticed on Gilles Twitter page
https://twitter.com/gillesaurejac that his NVMe booted into Sierra !
Something in his bootROM allows Sierra to SEE NVMe ?
============================================
I wonder if prior to his new NVMe DXE bootROM flash .. . that the installed PCIe M.2 blade he was using
WAS NOT VISIBLE in Sierra until
AFTER the flash ?
============================================
My 960 EVO M.2 was not visible until I did the kext replacement hack shown below.
( In Sierra. deleting the
IONVMeFamily.kext " and replacing it with the"
HackrNVMeFamily-10_12_3.kext ).
===========================================
Also, this from Gilles #13 post in this thread .. .
Note that once your cMP flashed with a NVMe modded BootRom, you will be able to :
-
run Sierra (like I did) or High Sierra, booted from a 4K compatible (and 4K formatted) NVMe drive. 4K capable NVMe SSD include any Kingston (A1000, KC1000), Toshiba (XG3-XG4-XG5), some WD / OCZ, some Intel datacenter SSDs.
- otherwise, run High Sierra from any 512b formated NVMe SSD, including any Samsung M.2 NVMe SSD.
===============================================================
I might
UNDO the
IONVMeFamily.kext " and replacing it with the"
HackrNVMeFamily-10_12_3.kext hack on another drive SSD 2.5" drive and try the flash
after quizzing poor busy Gilles re my Sierra setup.
