Clevo N870HP6 - files attached

You can try .
But i didn't need give up , in fact ,i already finished this mod case.
This is not a compicated menu struct ,it's easy .
so i don't know why it can't appear items if he confirm flashing bios is normal.

Maybe i forgot some important .

I thought maybe you probably got it modified correctly anyway, especially since you are a genius   I just wasn't sure what was going on here, and thought maybe he didn't understand you or understand how to flash mod BIOS etc (That's why I asked for stock package with both BIOS and batch file etc too)

Clevo BIOS is usually very easy, so I assume you already got it!  For chipset, sometimes "magic string" (01010100 to 01010101 random example in case "magic string" term is not what you call that mod/change) work OK by itself, other times 4602 to 4702 + "magic string" change is needed, which I assume you already know of course

If he's using stock package, and stock batch file to update the BIOS, then he needs to modify both BIOS files the same not just one BIOS, since both are usually called for flash in the standard batch file and smaller one is last which would overwrite any changes in this larger one he included once it wrote to BIOS afterward. Usually package is 4MB+8MB or 8MB+16MB. This 6MB must be a dump of BIOS region only maybe, from AFU or FPT, or other software?

How is he flashing in mod BIOS? Maybe flash update with mod is not completing properly?

Guys, thank you so much for your concern. I need bios with unhidden options cause I want to install Windows 7 (it needs csm option) and undervolt a little CPU I tried to flash stock package with changed only .ROM file. I will upload all files where I get at home.

[g-rynar]

Ok, here are all stock files which I am using to flash without any modifications:

If you manage to make this options unhidden I would be very grateful (especially CSM).

Flashing steps:
1. In current BIOS turn EUFI on
2. On shell type cd bios
3. MeSet.efi <- for cooling
4. after restart once again cd BIOS
5. FLASHME.NSH

[Lost_N_BIOS]

Thanks for package, I see the problem! Flashme.nsh does not call the BIOS you uploaded for modifying, checking etc.  
I think this is the problem with why you got nothing from genius239 BIOS, there is no BIOS flash command in the steps you outlined for the BIOS you provided.

Step 3, set ME functions (unknown what those are, but nothing to do with flashing BIOS)

flashme.nsh updates ME negating all of step 3. So step #3 should be done after flashME.NSH's ME Flash, if needed. Step 3 will not need redone anymore if you use flash.nsh instead

You can just use flash.NSH instead first of all, this way you are not always reflashing your ME for no reason.
I highly suggest this because it leaves no possibility for ME flash error which can brick the system.

Rename genius239 modified BIOS to 87TDES.502 and put in your flashing folder (copy or move original 87TDES.502 to another location)
* Edit - Or, actually, I would redo any and all mods, 87TDES.502 does not match / is not same at all as file BIOS.ROM which I assume you originally modified and or sent here for genius239 to modify.  Additionally, no files included ever call BIOS.rom to be used, only BIOS.All for the ME Reflash and 87TDES.502 for actual BIOS flashing, so I would not use this BIOS.ROM file for anything and would instead redo the mod on BIOS file 87TDES.502

If still no luck, or not all settings you need are shown, I will make mod BIOS for you, but his should be OK as he mentioned.  
I'm not sure what all he enabled, you'd have to ask him to specify.

Step #5 - FlashME.NSH = These commands / processes
@echo -off

set BIOSROM BIOS.ALL   << See, this BIOS called for the ME reflash, this step skipped in flash.NSH
set BIOS2ROM 87TDES.502  << This BIOS called for flashing BIOS (You did not provide this file, and probably did not rename your mod BIOS to this name) = so nothing modified flashed

#delete old MSDM file
if exist msdm.bin then
del msdm.bin
endif

# save MSDM
gmsdmx64

if not %Lasterror% == 0 then
goto end
endif

# update ME F/W   << Flashing ME FW
fpt -f %BIOSROM% -l 0x200000 -y

if not %Lasterror% == 0 then
goto end
endif

# update SBIOS  << Flashing BIOS - using BIOS2ROM = File named 87TDES.502
afuefix64 %BIOS2ROM% /p /b /n

if not %Lasterror% == 0 then
goto end
endif

# restore MSDM
if exist msdm.bin then
oaidefix64 msdm.bin /oa
if not %Lasterror% == 0 then
 goto end
endif
del msdm.bin
endif

# shutdown system
afuefix64 /s /shutdown

:end
@echo -on
---------------------------------------------------------------------------------------

For your reference, here is what is in flash.NSH, updating BIOS only, not touching Intel ME

@echo -off

set BIOSROM 87TDES.502  << This BIOS called for flashing BIOS

#delete old MSDM file
if exist msdm.bin then
del msdm.bin
endif

# save MSDM
gmsdmx64

if not %Lasterror% == 0 then
goto end
endif

# update SBIOS   << Flashing BIOS - using BIOS2ROM = File named 87TDES.502
afuefix64 %BIOSROM% /p /b /n  

if not %Lasterror% == 0 then
goto end
endif

# restore MSDM
if exist msdm.bin then
oaidefix64 msdm.bin /oa
if not %Lasterror% == 0 then
 goto end
endif
del msdm.bin
endif

# shutdown system
afuefix64 /s /shutdown

:end
@echo -on

Thanks for reply, but I had lost, when I was trying to analyze it. So finally, what should I do?
Rename BIOS.ROM (modified by genius239) to 87TDES.502, put away original 87TDES.502 and flash using FLASH.NSH?

[Lost_N_BIOS]

You're welcome! Sorry if that confused you, please read it slow, you will understand I think

Yes, your summary is correct. Without that, before, you were never flashing geniu239's BIOS mod, only incorrect stock BIOS each time.
If then success, and you see some new BIOS settings, but not all or not the ones you need, let me know and I can further mod for you or we can let Genius239 know and he can enable more settings for you if he wants.

Lost_N_BIOS, you were right. Until now I was flashing inproper file.. But now, when I was trying to flash I got this error: 18 - Error : Secure Flash Rom verify fail. And of course flashing was failed...

[Lost_N_BIOS]

Try this, put your 87TDES.502 from Genius239 into this folder, boot to DOS and run flash.batch
https://www.sendspace.com/file/gkfdjh

DO NOT run EEUpdate or anything else from within this folder, it's for another Clevo model.

If that fails, please test the following, and if you do not get any error, then use Genius239 BIOS for command that follows this one . Run all these, from within windows, at admin command prompt from this folders location - select folder, hold shift + Press right click, choose open command prompt here.)
fptw -bios -d dumpbiosreg.bin

If that dumps OK, please try this using Genius239 BIOS 87TDES.502
FPTw -bios -f 87TDES.502

If you get error 368, or any similar that say BIOS is protected region, use this guide I wrote starting at step #6 (Steps 1-5 get you this variable to use >> 0x9E0 )
https://www.win-raid.com/t3908f16-GUIDE-Grub-Setup-Var-Guide-Fix-Intel-FPT-Error-BIOS-Lock-Bit-Set-HSFS-W-Asus-or-Other-Mod-BIOS.html
So at the grub prompt your will type the following >> Setup_Var 0x0
This should already be disabled in your BIOS though, so I do not expect you will get an error like this for FPT command above.

Could you help me with commands in BIOS which allow me to perform that what you are saying? I had no system installed, so probably second method is unavailable. Am I wrong?
