[WORKING] Asus P8Z77-V: NVMe BOOT Support w. Download
#1
Hi Guys and Girls,

my dad i got got both computers with the P8Z77-V Boards.
The Samsung Sata Ssd in my dads computer died after 9 years (and 26TB written).

I recommended to buy a new Samsung 970 Plus NVME SSD together with a PCIe Adapter Card x4, hence its way faster than sata SSDs.

As you can imagine the Board got a nice UEFI but sadly cannot boot straight from NVME PCIe Slot (i should have known).
 Although it has an "PCIE Boot Enable" Option.

I tried to mod the Bios myself with no success. (noob)

Bios Link:  https://www.asus.com/de/Motherboards/P8Z...Desk_BIOS/         
Version 2104

I tried to mod using the following tutorial: https://www.youtube.com/watch?v=h_qRvvCWpWA  



AfuWin fails to flash "size error" and EZFlash App succeeds but with no effect on reboot. 

EZFlash2 from UEFI complains about security Validation. The P8Z77-V got no Flashback button.


Iam not sure if the modded .cap file is broken or if its just the flash process which fails.


I appreciate any help or modded Bios File with NVME Boot for the P8Z77-V

best regards

PS. i guess the SLIC topic is not the right one, but its the only open thread for this Board i can find using the onboard search.

Sometimes flashing a modded BIOS just works with an old BIOS Version. I had a P8Z77-M Pro with a broken flashback function and the only way I could flash a modded BIOS was with an old BIOS + FTK Toolkit or sth like that, I can't really remember...I think it was FTK8 or sth

Hey thanks for your Answer. Seems like FTK8 FlashTool is kind of a last option for desperate Flashers Tongue

Somehow i did it with the EZ Flash from the AI Suite 2.


I got a working NVME Boot now for my P8Z77-V computers.
I deleted the "PcieLaneDXE" register and added the full Addon " NvmExpressDxe_4". NVME boot is now working flawlessly.
I can not foreclose any bugs related to this, as iam a bios mod noob. So flashing on your own risks guys.

Link to the modded Bios cap + Asus AISuite with EZFlash / Update as ZIP.
https://www.file-upload.net/download-139...4.zip.html

How to Flash:

1) install the Asus Software
2) start the EZ Update / Flash from AISuite
3) select test1.cap
4 ) click next for bios check
5) delete test1.cap and rename test2.cap to test1.cap (replace bios files, after the software checked validation)
6) click update
7) wait 5 mins until you get a successfull message
8) reboot
9) have fun Smile
