@kyrios - PCIE x16 3.0 slot will be MUCH faster for NVME
But for x4 vs x16, PCIE 2/3 it would not matter, NVME only uses x4 so no matter the slot width 4/16 it will be same speed (only diff would be PEI 2.0 or 3.0)

And sorry, I meant x16 in the post you quoted above, not x1, left off the 6 Here's what I meant to say there >> I ask because even at x4 PCIE slot, speeds should be same as a x16 slot, because NVME only uses x4 no matter if it's in x4 or x16 slot.

Hello, can you please guide me to setup elitdesk 800 G1 with same bios 2.78 patching, so i can boot nvme drive
Thanks
-----------------

step by step please....

@elitepc - See post #2 in this thread, here is guide on how to use Grub/setup_var, you start at step #6, I've done 1-5 for you and info is on post #2
[GUIDE] Grub Fix Intel FPT Error 280 or 368 - BIOS Lock Asus/Other Mod BIOS Flash

After you've done stuff in grub from post #2, then you need to run this command with FPTw.exe and send me the created file >> FPTw.exe -a 0x5E0000 -l 0x8B0000 -d vol1.bin

Here is my copy/paste on how to use FPT to dump BIOS region, but you wont be doing that here, just run command above, I'm dropping this so you can find correct ME System tools package

This is the error shown

here is the backup

@kyrios @Lost_N_BIOS

Hi, I'm new here.
I have a hp 800 g1 with bios 2.78. I can use the vol1NVMEMM45.bin modification without doing the whole procedure. I get error 280 when trying to write it.
It is the same error from the beginning of the post.

thanks. sorry for my English.

@kyrios Do you happen do have the full BIOS dump. I think for me it would be easier to flash it via an external programmer. Would be a great help. Thanks!

Kind regards,
T

@radek68 @tiburcillo

Thanks
