NVMe functionality via ------> NVMe mod to run UEFI NVMe SSDs using module NvmExpressDxe_4.ffs dated 04/18/2018 inserted after CSMCORE for this Aptio IV UEFI/BIOS

Made with UEFI Tool v0.28 and UBU_v1_79_8










Enjoy your NVMe capable drive! [ latest edit October 10, 2020 with microcode v28 and EFI/ROM updates ]

Backup your drives and old bios BEFORE flashing...

Microcode updated to v 27; which mitigates Microarchitectural Data Sampling (or MDS) side-channel vulnerabilities in Intel CPUs in addition to Spectre/Meltdown vulnerabilties.

Hi hancor,
I'm new user here. Have been looking for working Z87-k nvme mod.
Thanks for taking your time modding the bios for Z87-k. I hope many other works on their pc but I have 'security verification failed' message popup.
What could be the reason?
Thanks

EDIT 1:
I tried remove the header capsule using method describe in Fernando thread below but now the message become 'reading failed' instead. The step is for ASrock board but i thought it would works being the same Aptio bios Z87 chip.

EDIT 2:
I'm going to try method in below pro.phantom thread and update later on suspicious of the error due to different bios size after i remove the header.

EDIT by Fernando: All 3 posts merged into 1 (to save space)

Thanks @Fernando for the edit.

Finally it's works!

I used the method to bypass security using FreeDOS and Afudos tool to flash the modified and headless z87k.rom.

My intel 960p shown as PATA SS so from your other thread someone ask the same 960 model and you replied yes right :)

Many thanks for @hancor and @Fernando for the original tips leading here!



For those looking for steps to flash BIOS bypassing security verification, refer to following thread
https://www.bios-mods.com/forum/Thread-G...res-UEFI-Aptio4

ps: is it allowed posting link to other forum :eek:

edit:
originally, i tried to flash using hancor z87k.cap file but the file is 2kb bigger than my original bios.
due to afudos file size check in the first step to flash the bios, it failed the check.
my 2nd tried using modified hancor z87k.cap become z87k-headless.rom using AMIBCP tool works.
I think its my luck also that the modified headless rom become exactly my original bios size (the header is 2kb).

download for the headless rom

@jiraiya78 Looks like I was late for the "digital party"....delighted that worked out for you!

Cheers

@hancor

Thanks!

@hancor I was wondering if you could please help me understand an issue here?

Originally the discussion started here https://www.overclock.net/forum/5-intel-...oftware-28.html
and ran into an issue with a bios modification for the z87-k microcode 22h

if I increase/change the clock speed from (Auto) to (manual) and increase from default clocks even 100Mhz higher than default (Auto) values the microcode patch changes to 12h in the bios cpu information, and if I leave the cpu clockspeed set to (Auto) then the microcode patch is listed at 22h in bios and I have no idea why its doing this? I was wondering if anyone with further understanding would help me?

Reason I'm after 22h microcode for asus z87-k bios is because apparently it has the best OC potential before 23h spectre/meltdown patches.

Hi @hancor . Is it possible to flash newer MEI FW onto this BIOS ? IF not, what does it take to make it compatible, for instance, with 9.1 or 9.5 FW ?

Ok, my Z87-K uses 9.0. Is it possible to mod the BIOS You made to be compatible with 9.1 or 9.5 ?

Hi again @hancor . Thank You for this modded BIOS. I just bought an PCIE to M.2 adapter and hooked up PCIE NVME drive and it works like a charm ! ;)

@hancor Is there any new microcode available for z87 and 4th series CPUs? I ve read that there are more holes in those CPUs but I'm curious if maybe intel release new microcode to mitigate (RIDL, Zombieload and 1 more which name I cannot recall now but its quite new ). Thanks ;)

Haven't seen anything vis a vis microcode updates for these and UBU_v1.76.0.1 has no news on this front either.

Cheers
