Hi Laffo,

I meanwhile can ship CH341A EEPROM Programmer or Bios from Germany... It allows writing Bios chips at will.

I concluded for the ASUS P8z77LX:
1. You cannot overcome the Bios Write Protection with the recent windows version of BUpdater or FTK-Master. AFUWIN can, but don't use it, it will swap some FF spaces with other Symbols and that will cause the Bios to be non-functional.
2. Flashing back to an old Bios Version without write protection is very risky. I tried P8Z77-V-LX-ASUS-0610.CAP and it did not start the system. Be aware that the old bios does maybe not support your Memory, CPU or GPU installed. Also, for Hardware Flashback, you will have to configure you bios to "Full USB initialization" and "Keyboard and Mouse" in advance and best use a PS/2 Keyboard unless it will initialize in the desired 1,5 seconds. Also it will be a blind task and thus I would not recommend it.
3. Nvme, NvmeSmm, NvmeInt13 does not work, only NvmeExpressDxE works and will show the device in the Boot List.
4a. Windows 7 did not work for me, no Install DVD/USB Medium I created was accepted as UEFI Bootable. In fact, it is easier to convert your existing Windows 7 as follows (You need Windows 10 bcdedit.exe for it): https://social.technet.microsoft.com/wik...on-to-uefi.aspx
4b. Windows 10 works on NVMe and z77! It will add a Boot Manager to your hidden EFI System partition. This Boot Manager also allows Dual Operating System Boot (Windows 7 / 10 on one NVme Drive)
5. UBU generates non-functional Bios-Files, they often even cannot be opened by Intel Flash Programmer Software. Better use MMTools to update and use the EFI Driver v13.1 of z97 Mainboards. It is reliable.
6. Updating Intel MEI is easy and worth it and works in any case, also with write protection, use FWUpdate.
7. Even if you use CH341A Writer always push "verify", unless it may not have been written correctly! I had that once.
8. If you have no EEPROM Writer you can order a programmed Bios Chip at (just build your personnal Bios with MMTools): http://www.biosflash.de/bios-chip-bauformen.htm

hello at all,
I have the same problem with "write-protected". I have an ASUS Z87-A, modded BIOS with the three nvme entries from a Z97-A, but I cannot flash them. If I try with AFU 5.05, I get follow message:

 Reading flash ............... done
3 - Error: ROM file size does not match existing BIOS size.
 

So are there other abilities to flash them without security or write protected?

then you might have exceeded the 8MB?

nope, the same size than the original. 8194 KB

maybe it means "I cannot overcome write protection"...
I can send you the EEPROM writer if you want, its an USB device and can write every Bios you want.

Do I need a EEPROM writer board (USB)?
You can send me a PM or share this here =)

Use FPT (DOS) or FPTW32/64 (Windows). You need the 9.1 or 9.5 version

Error 201: [FPTw64.exe] cannot be run on the current platform.
Please contact your vendor.
 

This was with Version 8. Then I found a 9.1 and 9.5 version and I tried again. There is a security lock and I'm getting error 208.

The Asus Z87-A should have the write protected descriptor on MEI or similar bios area and this don't allow to dump or flash bios.
You could try with MESET.exe from Clevo and see, after rebooting in Windows, if FPT is working.

The best thing, IMHO, is to flash chip via an external programmer. :)

I can't find the FPT tool. Maybe i'm tired.
I spent the whole night trying to mod the bios and flashing it with the usb flashback, but it won't flash. It blinks for 3 seconds and stops.

I own a Asus Z87-deluxe and try to get NVME running for my Samsung SP951. Don't want to buy a new mainboard or set. Maybe someone succesfully flashed a modded bios on this motherboard?

Users with an ASUS 7-, 8- or 9-Series chipset mainboard, which does not support the "USB BIOS Flashback" feature, should download the latest AFU tools from the AMI websites (>here< is the download link).
Our Forum member CodeRush has written a detailed guide, which can be found >here<.[/li][/ul]

The link for amiflash.zip doesn't work.
