I have a Dell Precision T5600.
I really need NVMe support so I can boot off my PCIe SSD. It is my understanding that there isn't any technical issues that prevent this support being made available.
I would fix it myself however "signed firmware update" makes it difficult to upgrade the firmware with the needed efi firmware.
Its more than a little troubling that I own this machine and would like to use it to its full potential, but Dell seems reluctant as far as I can tell to make the UEFI upgrades available.
I would like to be provided a BIOS update that has the features I need, or get the BIOS unlocked so I can flash the update myself, or if there is some other means to accomplish booting an Intel 750 series SSD on a Dell Precision T5600 please direct me to the procedure required.
I followed the suggestions in this good article. But I wasn't successful.
The two issues I encountered were
1. I couldn't get the USB drive to show as a UEFI boot option, only legacy.
2. When I select the PCIe SSD drive as the destination for a Windows install, windows presents an error that it cannot boot from this drive, even thought I've seeded the install with all the drivers Intel provided.
Thanks for any help or further ideas on this.
