Hi forum:

I got a Lenovo Ideapad Miix 320 which is a 2 in 1 (Tab and PC), it has a Insyde H2O UEFI-BIOS, and I want to know if is possible to mod the UEFI-BIOS to update CPU microcodes (Spectre and Meltdown), Intel ME, Uefi and Legacy modules...

Here is the support webpage of the Miix 320and UEFI update is here

Thank you so much for your time and hep, regards.

Bump!!, at least, can you tell me if is possible to update/mod the UEFI-BIOS?

Thank you mates, regards.

@RaskaipikaFWR - Please do the following

If you have already modified the BIOS in ANY way, you will need to re-flash it back to factory defaults using factory method (NOT FPT)!!!

If you do not have Intel ME drivers installed, install them now from your system driver download page, then start over here after reboot.
Check your BIOS' main page and see if ME FW version is shown. If not then > DOWNLOAD HWINFO64 HERE <

Once HWINFO is open, look at the large window on the left side, expand motherboard, and find the ME area.
Inside that section is the ME Firmware version. Take note of the version. (ie. write it down or get a screenshot)

Once you have that, go to the thread linked below, and in the section "C.2" find and download the matching ME System Tools Package for your system.
(ie if ME FW version = 10.x get V10 package, if 9.0-9.1 get V9.1 package, if 9.5 or above get V9.5 package etc)
> DOWNLOAD " ME System Tools " packages HERE <

Once downloaded, inside you will find Flash Programming Tool folder, and then inside that a Windows or Win/Win32 folder (NOT x64).
Highlight that Win/Win32 folder, then hold shift and press right click. Choose "open command window here" (Not power shell! >> * See Registry file below *).

If you get an error, reply to this post with a screenshot of it, OR write down the EXACT command entered and the EXACT error given.

((If "open command window here" does not appear, look for the "Simple Registry Edit" below...))

Step #1
Now you should be at the command prompt.
You are going to BACKUP the factory un-modified firmware, so type the following command:
Command: " FPTw.exe -bios -d biosreg.bin "

>> Attach the saved "biosreg.bin ", placed into a compressed ZIP/RAR file, to your next post!!! <<

Step #2
Right after you do that, try to write back the BIOS Region dump and see if you get any error(s).
Command: " FPTw.exe -bios -f biosreg.bin "
^^ This step is important! Don't forget! ^^

If you get an error, reply to this post with a screenshot of it, OR write down the EXACT command entered and the EXACT error given.

Here is a SIMPLE REGISTRY EDIT that adds "Open command window here as Administrator" to the right click menu, instead of Power Shell
Double-click downloaded file to install. Reboot after install may be required
> CLICK HERE TO DOWNLOAD CMD PROMPT REGISTRY ENTRY <

If the windows method above does NOT work for you...
Then you may have to copy all contents from the Flash Programming Tool \ DOS folder to the root of a Bootable USB disk and do the dump from DOS
( DOS command: " FPT.exe -bios -d biosreg.bin " )

I think unlock is in sub_272F4, but I am not 100% sure. So once we figure out how/if you can flash mod BIOS without flash programmer, then you will have to ask the guys at BIOS-mods.com forum to unlock this since I am not 100% sure.

@RaskaipikaFWR - You're welcome! It depends on what post of mine you were asking about, I mentioned unlock in regards to both of those things
BIOS chip is there, show me images of the board, both sides, I will circle BIOS for you. Great you already have programmer and clip! lets find the BIOS chip, then you can just dump anyway and ask the guys at BIOS-mods to unlock the BIOS menu for you.
