@Svan - No need to give up so easily Boot audio can be disabled, just needs to be done in another area instead then (instead of what AMIBCP changes). This is just as easy to edit, if you want it done I can do it for you.
Reset CMOS isn't going to do anything more than loading optimal defaults.

Here, disabled everywhere now (Setup, AMITSE/SetupData, and NVRAM x3 + x7) -

@Lost_N_BIOS

Great thanx a lot I will flash it now and report again (need to dissably all again ). You can delete the link since you forgot pass

I have a question. I forgot to disable XTU undervolt before doing main backup with Flashcat (default settings were already done in bios since original bios update v310 but didn't do a reset default again before doing backup).
Does it matter because undervolt is stored somewhere in a chip memory ? (for info needed to set again undervolt in XTU after I flashed the 1st bios mod).

For example I discoverd on the other notebook. If you had set undervolt in XTU and you do a macrium backup (to may be restore it later) and install a full fresh windows, then the undervolt is set for ever without installing XTU,
until you load default settings or update your bios

Greetings.

Update : It's working 100% you are a genius. Thanx a lot to for your work on the extra missing settings

Sorry I forgot pass, file removed! Do you want me to unlock FD, so you can flash mod BIOS via FPT instead of using programmer always?
Sorry, I don't know anything about XTU or how it interacts with the BIOS (Or not, I mean, if it even does). From what you mention it sounds like it actually changes the BIOS settings, since it remained until you re-loaded optimal or reflashed BIOS.
I'm not sure what your question is about this though, set it however you want with BIOS or with XTU.

Thanks for report back, good to hear the Boot Audio is now disabled! If you want unlocked FD I can do, then that will be last time you'll need to program in BIOS.
I can also unlock BIOS (only as I mentioned in post #2) so you can see all settings like you see in AMIBCP, if you want let me know [thuimbs-up]

@Lost_N_BIOS

Hey buddy,

Don't need to unlock FD to use FPT. I will not touch the bios until there is a major update to do
I think about XTU it's ok even it may using a hidden hardware memory it's not in the bios main memory for sure. If it was the case, I will get my undervolt settings back after modded bios flash.
May be it's a hidden bios reserved memory for XTU. Didn't found info on google.

Yes sure I will tell you if I need extra. Thanx a lot again

@Lost_N_BIOS

Hi buddy,

I would like to ask you if you have spare time to do the firmware version 312 before I open my laptop to dump the firmware.

This time if possible I would like to have :

- EFI - OROM IRST : 17.8.3.4687
- Microcodes updates (CPUID : 906E9)
- Unlock FD to be able later to flash with FTP
- Disable audio boot sound by default

Hope you doing fine, wish you a wonderfull New Year and congrats for your moderator promotion

Greetings.

PS : May be need to move this thread to "BIOS modding request"
