Having issues flashing a P8Z77-V LX BIOS. I am trying to update my bios and started by flash a new existing bios from someone else but don't see the new splash screen that is suppose to be there after flashing. I suppose something is gone wrong flashing. I am using freedos to flash the bios and get the following output:

C:\TEST>AFUDOS.EXE morph2.rom /GAN

any help appreciated.

You just want NVME Mod BIOS, correct? If yes, please flash to latest BIOS version stock BIOS using EZ flash and USB, then do the following

Fortunately there was a DOS version. I assume you need the bin file:
https://drive.google.com/file/d/1X8xX6Xx...5A4k9HUYJW/view

Main thing is to enable NVMe support indeed but any other stability and security improvements are welcome.

thx!

@osrcs - Why fortunately DOS? But yes, you can use DOS if you want.
I don't need your biosreg.bin file yet, you will likely make another later, that I will want. Right now, I'm waiting on an image of the error you get, if any, when you try to write back the file you just dumped (see the bold part of the instructions )

And, please confirm, which BIOS exactly did you flash at first post example? Sorry, I thought you used MORPHEMIC's BIOS at first post of this thread, which has the logo change I mentioned, but I just now see you do not have that model of board so you wouldn't be able to flash that BIOS.

@Lost_N_BIOS

Do I need to supply more info? If so which?

thx!

-------------------

Looks like I finally made a step forward. Need to downgrade the bios before flashing the modded bios:

- fpt -bios -d stockbios.rom
- with ezflash flash this stock bios from asus: P8Z77-V-LX-ASUS-1603.CAP
- make changes to stockbios.rom and save as modbios.rom
- fpt -bios -f modbios.rom

Now it does not give an error. Will check as soon as my nvme drive arrives.

Are there any other bios mods that are advised?

@osrcs - Thanks for the info, and sorry for delays (I can't keep up here with all posts )

You can only use the BIOS for your model, the title simply means that all variants are discussed in that thread (it shouldn't have all been merged together is the issue there!) So, nothing was flashed, it only appeared to flash, lucky for you

Please slow down, stop trying to force things, wait for help, before you brick your system, especially with FPT!!

Please flash latest BIOS using EZ Flash, then do the following to remove 280 error - You can start at step #6, I've gathered info you need below
[GUIDE] Grub Fix Intel FPT Error 280 or 368 - BIOS Lock Asus/Other Mod BIOS Flash

Rename your .efi file to >> Shellx64.efi

Variable to change at grub >>
SMI Lock, VarStoreInfo (VarOffset/VarName): 0x88
BIOS Lock, VarStoreInfo (VarOffset/VarName): 0x89

So, at grub prompt you will type the following, one line at a time, enter between each (case sensitive)
setup_var 0x88 0x00
setup_var 0x89 0x00

Then reboot, dump BIOS again with FPT, send me that or modify yourself, then flash back with FPT
