Managing BIOS settings on Asus NUC devices with PowerShell

 

In this post I will explain you how to manage BIOS settings for Asus NUC devices.

Context

- You have some Asus NUC devices

- You want to apply specific BIOS settings

- You want an automate way

The solution

To manage BIOS settings we will use the iSetupCfgWin64 tool.

To get it proceed as below:

1. Go to this link

2. Select ASUS NUCs

3. In Product series, select NUC Kits

4. In Product model, select

5. In my case it's ASUS 13

6. Go to Driver & Utility

7. Go to BIOS & FIRMWARE

8. Select your model

9. In my case it's NUC13L3KV5

10. Download NUC Firmware Integrator Tool

11. Go to the downloaded folder

12. Go to iSetupCfg

13. Go to iSetupCfgWin

14. Go to X64

You will then need below files:

- iSetupCfgWin64.exe

- amigendrv64.sys

You can also get the last version from my GitHub here.

Going further

In my post here, you will see how to convert Asus NUC BIOS settings t a PowerShell array.

This way you can easily filter on settings.

See below an overview:

Export BIOS settings

Export existing BIOS settings config

We will use the iSetupCfgWin64.exe and pass below parameters:

- /o

- /s: indicates txt file containing the config 

- /b: export boot order controls

See below the full cmdline:

See below an overview of the txt file:

Export settings different from the default

We will use the iSetupCfgWin64.exe and pass below parameters:

- /o

- /s: indicates txt file containing the config 

- /b: export boot order controls

- /ndef: export only those settings whose current value is different from the default

- /q: silent

See below the full cmdline:

Get specific setting value

We will use the iSetupCfgWin64.exe and pass below parameters:

- /o

- /ms: Indicates Map String 

What is map string ?

Let's take again a config we have exported to a txt file.

For each parameter you will see option called Map String.

For instance below is the config for USB boot: 

The Map String to specify is SPG0DA.

To get value of this setting the cmdline to use is:

See below the result:

Set BIOS settings

To set BIOS settings we will need below files:

- iSetupCfgWin64.exe

- amigendrv64.sys

Set a specific parameter

We will use below parameters:

- /i

- /ms: Indicates Map String 

- /qv: value of he parameter

- /cpwd: specify the BIOS supervisor password

Let's take our previous example with USB boot.

See below the config:

The Map String to specify is SPG0DA.

Available values:

- 01: Enabled

- 00: Disabled

Now we want to enable this parameter.

The cmdline to use will be:

Set setting(s) without BIOS supervisor password

For this we will proceed as below:

1. Configure parameter iSetupCfg Password Check to Bypass

2. The password to use is*: admin

* it is a standard default password

3. The cmdline to use will be:

Set all BIOS settings from a txt file

There we will set BIOS settings from a txt file.

We will proceed as below:

1. Export existing config to txt file

2. Manually change settings in txt file

3. Set BIOS settings using the new txt file

OR 

1. Manually configure settings on a device

2. Export existing config to txt file

3. Set BIOS settings using the new txt file

The cmdline to use will be:

Set all BIOS settings without BIOS supervisor password

For this we will proceed as below:

1. Configure parameter iSetupCfg Password Check to Bypass

2. The password to use is*: admin

* it is a standard default password

3. The cmdline to use will be:

Set BIOS supervisor password

In this part we don't have a BIOS password yet.

1. Configure parameter iSetupCfg Password Check to Bypass

2. The password to use is*: admin

* it is a standard default password

3. The cmdline to use will be:
