B660H7-M20 BIOS and iGPU

[dot7ero]

Hello,

i bought a MD 35354 with the motherboard B660H7-M20, i7-12700 and RTX 3060ti.
if I attach the hdmi cable into the motherboard port I have no signal and from the bios I don't see any menu to enable or disable iGPU.

Is it set to automatic into hidden options on the bios?

does it only work if there isn't graphic card mounted on motherboard?
can you send me the latest version of the bios that maybe fixes the problem?

I have version B660H7W0X.109

Thanks

i have another question . but I need expert.

if I want restore ECS bios wich options do you suggest me?

AfuEfix64.efi ECS.ROM /p /b /r /x /l

or 

Afuefix64 ECS.ROM /P /B /N /K /X

?

in the first case not reset NVRAM but preserve SMBIOS and program all holes

- /L   Program all ROM Holes.  

- /R   Preserve ALL SMBIOS structure during programming 

in second case reset NVRAM but 'not program all holes'

- /N   Program NVRAM    

- /K   Program all non-critical blocks and ROM Holes.  

Thanks

but I think the best options are like this to reset the bios to factory ECS's settings

Afuefix64 ECS.ROM /P /B /N /L /X

[dot7ero]

I'm not sure if this option should be used too
- /CAPSULE Overrides Secure Flash policy on Capsule

Hey, did you ever manage to install the original BIOS from ECS and if so, can you tell me how?

I have a similar problem and to fix it I need the BIOS from ECS installed, but I'm stuck on the Medion BIOS Version 112 I believe.

Thanks in advance 🙂

Hey there,

for everyone needing still help i got the ECS Bios on my Medion Board now. 

What you ll need:

- a cheap CH341 Programmer Kit (mine was around 9€ at the big A)

- Freeware like ASProgrammer or Neoprogrammer

- good Eysight to read the Bios-Chips ID (mine was a MX77.....)

- you search that ID an verify, that your Programm u just downloaded has this ID in the ID List or you sesrch via google for an List which has this ID on it and Copy this one into the Programs Folder

- make sure the USB CH341 Programmer gets recocnized in Windows with a Driver you ll most likely have to download too (i had to try 2 different once)

- install at least 24 and 8 Pin from the Powersupply to the board but dont start the board

- Connect the red Pin1 Cable of the clamp onto the Bios Pin 1 (marked by a small dot)

- i recommend to watch at least 1 or 2 Videos of how to setup and use the Ch341 Programmer before getting started

Good luck everyone
