DMIEDIT (also known as AMIDEDOS or AMIDEWIN) 5.x is an official American Megatrends (AMI) utility designed to modify System Management BIOS (SMBIOS) data—commonly known as DMI information—on AMI Aptio BIOS systems. It allows technicians to update system information like serial numbers, asset tags, and model names. Core Functionality
Purpose: Updates motherboard DMI fields (Manufacturer, Product Name, Serial Number, UUID).
Version: The 5.x version is specifically designed for Aptio V BIOS.
Environments: Supports Windows (AMIDEWINx64) and EFI Shell (AMIDEEFI). How to Use DMIEDIT 5.x (Windows Method)
This is the preferred method for editing DMI data from Windows 10/11.
Preparation: Download the DMI Edit utilities [such as from Schenker Technologies or NCR Voyix](1.2.2, 1.4.5) and extract the files. Access: Open the Command Prompt as Administrator.
Navigate: Go to the folder containing the executable (e.g., cd C:\AMI).
Read Data: Run amidewinx64.exe /ALL to view the current DMI information.
Edit Data: Use specific commands to update fields (see list below). Key Command-Line Arguments (AMIDEWINx64) System Serial Number: amidewinx64.exe /SS "[new_serial]" Product Name: amidewinx64.exe /SP "[new_product_name]" Manufacturer: amidewinx64.exe /SM "[new_manufacturer]" System Asset Tag: amidewinx64.exe /SA "[new_tag]"
UUID: amidewinx64.exe /SU UUID (Automatically generates a new UUID) BIOS Version: amidewinx64.exe /IV "[new_version]"
Example: To change the Product Name, type amidewinx64.exe /SP "MS-7E26" and press Enter. Important Precautions
Run as Administrator: The tool will fail if not run with elevated privileges.
Reboot: Changes may not be visible until the system is restarted.
NDA Information: Note that official AMI Aptio V DMIEDIT documentation is often under NDA (Non-Disclosure Agreement). To make sure I give you the right commands, I need to know:
What is the specific brand and model of the motherboard or laptop? (e.g., MSI, HP, Asus) dmiedit 5.20
Which DMI field are you trying to edit (Serial Number, UUID, Product Name)? Are you doing this in Windows or via a bootable USB?

DMIEdit 5.20 (specifically AMI DMIEdit/AMIDEEFI) is a powerful DOS/EFI/Windows utility designed by AMI (American Megatrends Inc.) to view and update the System Management BIOS (SMBIOS) data within the BIOS, such as serial numbers, asset tags, and model names.
Here is a full overview post based on using DMIEdit to customize your system. Complete Guide to DMIEdit 5.20 for Insyde/AMI BIOS
Updating the DMI (Desktop Management Interface) data is crucial for system builders, IT technicians, or anyone who has replaced a motherboard and needs to restore the original manufacturer information (serial number, UUID). What Can You Edit? System Serial Number: Updating the main unit serial. Asset Tag: Tracking company property. Board Serial Number: Identifying the specific motherboard. UUID: Unique Identifier. Prerequisites DMIEdit Utility: Usually available in Windows (
) or EFI Shell versions. Look for amidediwin64.exe or amidediefi64.exe.
Administrator Rights: Windows tools require elevated commands.
Correct BIOS: Primarily intended for AMI and some Insyde implementations. How to Use DMIEdit (Windows AMIDEWINx64)
The most common method is using the Windows-based command-line tool. 1. View Current DMI Data Run this command to see all current DMI information: amidewinx64.exe /dump Use code with caution. Copied to clipboard 2. Update Serial Number
To update the system serial number, use the /SS switch followed by the new string in quotes: amidewinx64.exe /SS "YourSerialNumber" Use code with caution. Copied to clipboard 3. Update Product Name amidewinx64.exe /SP "NewProductName" Use code with caution. Copied to clipboard 4. Update Board Serial Number amidewinx64.exe /BS "NewBoardSerial" Use code with caution. Copied to clipboard 5. Update Asset Tag amidewinx64.exe /AT "NewAssetTag" Use code with caution. Copied to clipboard How to Use DMIEdit (EFI Shell)
If Windows is not installed, you can use the EFI version, which is often more reliable. Create a bootable USB with EFI Shell. Copy amidediefi64.efi to the USB. Boot your computer into EFI Shell.
Run commands similarly, for example: amidediefi64.efi /SS "NewSerial". ⚠️ Critical Warnings
Irreversible Changes: Once a DMI field is updated, it is permanent unless flashed again.
Correct Information: Ensure you type the serial numbers exactly, as this information is used for warranty validation by manufacturers.
Safety: Do not use random DMIEdit versions; use the one specifically provided by your motherboard or laptop vendor.
Disclaimer: This post is for informational purposes for technicians. Improper use of DMIEdit can lead to corrupted BIOS data. To give you the most accurate command, could you tell me:
