Putting a jumper on to these pins allows the Intel Management Tools to fully read the BIOS, but the Intel Flash Programming Tool (fpt.exe) is not able to write back to it, and displays the message: C:\Intel ME System Tools v8 r3\Flash Programming Tool\Windows64>fptw64.exe -bios -f nvme.bin The HP 8300 motherboard has a similar function called FDO (Flash Descriptor Override): On the Dell OptiPlex 7010 I was able to put the machine into service mode and gain full read and write access to the BIOS. Why is the HP Compaq 8300 Difficult to modify Here is an image of the motherboard from a 790 SFF: Once those are out of the way, you can find near the RAM slots. If you are upgrading a Small Form Factor machine, the service jumper is in an awkward position which will require you to remove the Optical Drive and Hard Drive cage to access it. Locate the two pin service connector and put a jumper on it.Now that you have the machine prepared, you need to put the machine into service mode before you can proceed:
Next, download the Intel Management Engine System Tools v7 r2, which contains the tools required to flash the new bios.Īlso download the NVME Driver which will be injected into the BIOS Image.įinally you will need UEFI Tool 0.28 to make the actual BIOS modification.
But instead of installing them from Dell, get these more up to date drivers from Lenovo.

If you have a SATA SSD already then the speed increase is certainly worthwhile, but perhaps not essential.įiled Under: How To Tagged With: NVMe Install and boot from an NVMe SSD on a Dell OptiPlex 790 or 990 If your existing machine has a mechanical hard drive the speed boost will be immense. ConclusionĪdding NVMe support to the Lenovo ThinkCentre M92 provides a truly fantastic value upgrade. If anyone tries it out I would be interested to hear your results. I don’t know if this upgrade would work on those machines, but I suspect that it would. The BIOS file for the Lenovo ThinkCentre M92 is the same file issued for:
Locate the two pin ME_DIS jumper and put a jumper on to it.Under normal circumstances it is not possible to read or write to the BIOS freely. So the path should be:Ĭ:\Intel ME System Tools v8 r3 Put the machine into Service Mode Intel Management Engine System Tools v8 r3Įxtract the Intel Management Engine System Tools to the root of your C Drive.Installing your operating system to the new SSD.Writing the modified BIOS back to the system.Adding NVMe driver support into the BIOS backup.Upgrade to the most recent BIOS from Lenovo (9SKT9CA).This process involves the following steps: I used this Samsung 970 EVO Plus from Amazon, but any NVMe SSD would work. In order to do this amazing upgrade, you will need a few things: Can this be done on other Lenovo Desktops?.Modify the BIOS and Inject the NVMe Driver.
