@100PIER:
UBU is using binary patterns for recognizing known drivers and has no signature for NvmExpressDxe_Small yet.
UEFITool screenshot looks good.

@Fernando
I have flashed the modded BIOS with the "small" NVMe module for my ASUS P8Z77-V Deluxe platform.
All is working fine.

However, I don't observed any significant boot time improvment with the "small" NVMe module.
Are you sure you tested with strictly the same conditions (for instance M-Spectre Protection disabled/enabled) ?

On my side Meltdown-Spectre Protection Disabled does offer 36s booting time, vs 46s booting time when Protection is enabled !

@100PIER:
In my experience once you are on NVMe, boot time is significantly dependent on other, slower components. Even discrete graphics card initialization takes longer than NVMe initialization, although both are connected directly to the PCIe bus.
Note that the goal for NvmExpressDxe_Small was size reduction that also resulted in slight performance improvements. I however don't expect significant boot time performance improvement in most cases.

Hi Fernando
Ok so the 960 pro arrived today, that took forever long story.

I tried using Samsung magician to clone the uefi win 10 copy onto it but it is not being detected as a boot device.
I am going to see if The Z820 will detect it via USB uefi win 10 stick.
I did update to v3.93 bios then I inserted your nvme module.
I have disabled fast boot and secure boot in my bios.
I may have to re do this bios hack and upload a zip for you to check if I inserted it correctly.

Will post a link in next 24 hours if you can help I really appreciate it
Thank you

Ok so I have inserted uefi USB win 10 and when I get to hdd it can see 960 pro 476gb . So I have selected it and it is loading .............
Fingers crossed the bios sees it when it restarts

No go .....
So when I insert a USB stick with win 10 UEFI , and then select a disk to install on the 960 pro is there .
But as soon as it installs to the 960 pro and re boots it can’t see the 960 pro ?
Does this ring any bells at your end ?

Hi Fernando
Here is a copy of the modded z820 bios using v3.92A.
Would you mind checking that i inserted it correctly .
I re did the hack with the small nvme and still the bios wont pick up the 960 pro.

I have a laptop Asus G501JW with 4x Intel generation processor.
My preinstalled SSD got some errors and became superslow(like 10 years old hdd) so I bough without any doubt Samsung 960 EVO.
And now I am here.

My motherboard doesn't work with NVMe, so I followed the guide to make my own modded bios. Everything was looking great till the moment of flashing it. My Flash utility on motherboard seems to care which version of BIOS I am going to install and not allow modded one, because value of date is unknown, as well as other 3 field in preview of flash utility (manufacturer, version). Exact error sounds 'The BIOS file is older than the current version'.
I couldn't find anywhere on forum any helpful information. Maybe I need to use another editor or choose different format to modify those fields? Choose another bios update utility?
This topicl describes different version of BIOS then I have (I have more earlier version, white screen with dark letters), so I am not sure I can use any information provided.

What could it be then that "windows Boot Manager/960 Pro " is not visible?
Is it possible that this cant work on my system ?
i am happy to go back to the 950 pro but................. i would rather not (:
I have tried so many different bios settings
I have tried usb uefi fresh install + magician clone from a working uefi win 10.
what to do..............

I just re did everything from beginning

Rufus
1) open rufus
2) load win 10 iso
3) gpt + fat32

start > copied to usb

4)Started z820 with nvme 960 + win 10 usb
5) Install win 10 to 960 as per start post instructions
6) z820 reboots after installation but cannot see the 960 in BIOS

i have checked and triple checked everything i don't believe its possible on z820 ! Unless you have other suggestions !

Thanks
