What is BMT ?

The BIOS Modification Tool allows end users to modify parameters in the System BIOS without need to recompile the BIOS. All modifications are carried out on the binary file copy of a System BIOS.

Default values for BIOS setup parameters, visibility of menu items, default boot order, sign-on and setup strings, and SMBIOS string data can all be modified with this single tool.
The BIOS Modification Tool is a common utility to for all ADLINK's x86 based modules COM/SMARC/Q7 products.
The utility is free to use but will only work on ADLINK enabled BIOS.

Features

• Rename Menu entries: Allow you to renew each node or entries
• Hide Menu entries : hide entries to avoid user from modifying entries or just simplifying the BIOS setup
• Change Defaults boot order: configure default bootup values to optimize your system
• Change DMI Information: modify logistical DMI data, such as OEM strings
• Track Changes: save a copy of all items that can be configured.
• Import setting: import your custom setting copy to restart where you left of

Getting Started

How to get the BMT utility

1. Before start BMT utility, please download & install Microsoft Visual C++ Redistributable for Visual Studio 2013 or above version.

2. ADLINK's BIOS Utilities are available on this link

The file to download is a zipped binary, download, unzip it and copy to files to a dedicated directory. There is no need for install, the file can be executed in place simply by double clicking it.

Note that the utility is only capable of modifying a binary filecopy of the target System BIOS. After modifying, the binary is saved and than has to be flashed into the target module.

So most of the below BIOS modification would normally be carried out on a standard laptop or desktop computer.

Basic principle

To modify a BIOS you will go through the following major steps

• Extract the BIOS from a target module and create a file copy
• Move the file copy to a host machine (or just use the target module for that) and modify the binary file copy with the BMT utility
• Flash the modified BIOS in the target module and test it

How to get a binary copy of your target BIOS

Simplest way to get a binary file copy of the BIOS of the target COM this is to run Windows 7/8/10 on the target and extract the module's BIOS with a AMI's AFUWIN utility.

The AFUWIN module can be downloaded here :

https://www.ami.com/download/aptio-v-ami-firmware-update-utility/

This AFUWIN program can be used to both extract and flash BIOS.

How to Flash BIOS

It needs using AMI flash utility to upgrade BIOS, please refer to the following steps:

1. Please download AMI Firmware Update utilities:

   ​ https://ami.com/en/?Aptio_V_AMI_Firmware_Update_Utility.zip

2. Please copy AMI Firmware Update utilities “AfuEfix64.efi” & modified BIOS to USB drive.

3. Please enter BIOS menu and choose “UEFI: Built-in EFI Shell” in Override” to go into BIOS Shell mode.

4. Please enter the following commands to look for the files on USB drive:

Shell> fs1:
FS1:\> ls
   10/15/2018  17:31             555,632  AfuEfix64.efi
   10/15/2019 17:30         16,777,216 1012VC0SS60E110.ROM

        2 File(s)  17,332,848 bytes

Note: you can see the location of USB drive after enter Shell module, ex: fs0 ~ fs3

6. Please enter following command to flash until the utility shows “Process completed”
