AMI Flasher is a utility program that helps you to update your BIOS — the code that runs the first moment you boot your PC. It was created by AMI to support flashing AMI BIOS based data files.
The BIOS code is stored on the motherboards on Flash chips since its introduction in 1993.
Over the years AMI has released DOS, Windows and Linux based flashers for different versions of AMI BIOS and AMI UEFI BIOS.
The DOS based versions can’t be run from Windows or other operating systems. You’ll need to create a bootable DOS disk.
Please read our How to flash your bios FAQ to correctly use the AMI Flashers.

(Examples: how to update your BIOS, how to identify your motherboard)
In most cases BIOS cores were made by Award Software, American Megatrends Inc. (AMI) or sometimes by Phoenix Technologies. So it’s not too complicated to figure out which BIOS update utility you need to flash your BIOS. There are also non commercial tools, like UniFlash and flashrom, which are suitable for all brands of BIOSes.
Note: This page doesn’t cover EFI/UEFI, all tools and recommendations are for classic BIOS.
prerequisites and precautions
- Be sure to have the right BIOS update file / image for your mainboard
- Your system components shouldn’t be overclocked
- Your system must run really stable
- If you’re going to flash on Windows, close all applications
It is highly recommended to flash on DOS as flashing the BIOS on Windows is more risky.
Flashing the BIOS happens on your own risk — be sure to download the right BIOS file and the suitable flash utility. This website and it’s owner is not responsible if you brick your motherboard!
how to flash the motherboard BIOS
Just download the appropriate zipped BIOS file, unpack it, rename it to something simple like bios.bin (Award, Phoenix — Award) or bios.rom (AMI, Phoenix) and use the suitable flash tool listed below.
After updating the BIOS successfully shut down the PC, disconnect the A/C power cable (or switch off power supply) and make a Clear CMOS. Reconnect to A/C, turn on the PC, enter the BIOS setup (mostly via «del» or «F2»), chose «Load Optimized Defaults» (or similar) and save/exit setup.

Below you will find a selected utility that is designed for use with Zida Tomato motherboards. Usually these are utilities used to update the firmware or BIOS of the motherboard. Remember that flashing takes place at your own risk. If the update fails, contact a suitable IT service center.
Most utilities come from the turn of the millennium and require booting from a DOS floppy disk ideally in MS-DOS version 6.x without the established himem.sys and without emm386.

BIOS/UEFI Utilities for Aptio® and AMIBIOS
Custom UEFI and BIOS utilities for Aptio and AMIBIOS simplify the development and debug experience. AMI’s Aptio firmware offers an easy transition to the Unified Extensible Firmware Interface (UEFI) specification, giving developers all the advantages of UEFI – modularity, portability, C-based coding – while retaining easy-to-use tools that facilitate manufacturing and enhance productivity. AMI’s rich set of utilities for BIOS ROM image customization without rebuilding the firmware provide a clear advantage in reducing both time and cost.
AMI Firmware Update (AFU)
AMI Firmware Update (AFU) is a scriptable command-line utility for DOS, Microsoft Windows®, Linux, FreeBSD and the UEFI shell. Utilized for factory or field BIOS updates, AFU is flexible enough to update the entire Flash part or only a portion. It programs the main BIOS image, boot block or OEM configurable ROM regions.
AMI BIOS Configuration Program (AMIBCP)
The AMI BIOS Configuration Program (AMIBCP) for Aptio enables customers to modify parameters in a BIOS ROM without rebuilding from source. Developers can modify default values for BIOS setup parameters, modify default boot order in BIOS setup, view and edit sign-on and setup strings, and edit SMBIOS string data.
AMI Setup Data Extraction (AMISDE)
AMISDE is a command-line tool for exporting setup data from an Aptio ROM image, including spreadsheet applications such as Microsoft Excel®. It generates a helpful summary report of BIOS setup parameters and default values that enhances productivity in testing and manufacturing.
AMISLP
AMISLP allows the insertion of Microsoft System Locked Pre-Installation (SLP) key files into the BIOS image. SLP keys are used for OEM activation of Microsoft Windows® 7 and Vista®. For Windows® 8.1 and Windows® 10, the OEM Activation 3.0 eModule is used in conjunction with AFU v2.35 or greater.
Change Logo
Change Logo allows developers to easily change logos displayed by Aptio at boot. The full screen “splash” logo and small logos appearing on the main screen during POST can be replaced with custom logos. Change Logo also allows logos to be extracted from existing Aptio ROM files.
AMI Utility Configuration Program (AMIUCP)
AMIUCP is a utility that is used to pre-configure the Aptio Flash Utility (AFU). Users can insert and exchange the default command string and ROM image used in AFU to create a customized version of the utility. AMIUCP supports AFU v2.35 or AFUWINGUI v1.12 or later.
Desktop Management Interface Edit (DMIEdit)
DMIEdit is a scriptable command-line utility for DOS, Microsoft Windows®, Linux and the UEFI shell. The Desktop Management Interface Editor for Aptio enables developers to modify strings associated with platform SMBIOS tables (System, Base Board, Chassis, OEM string, etc). In manufacturing, use DMIEdit to embed platform serial numbers, UUID and license keys into the SMBIOS table, which identifies platforms to management software.
Module Management Tool (MMTool)
Aptio’s Module Management Tool (MMTool) allows developers to manage firmware file modules contained within an Aptio firmware ROM image. Use MMTool to extract, replace and insert binary components such as modules, Option ROMs, microcode patches and ROM holes using its graphical or command line interface. With MMTool, developers can also create reports on the contents of an opened ROM image.
AMI UEFI ROM Dissect Tool (AMIRDT)
The AMIRDT utility makes it easy for developers to dissect a UEFI ROM and produce related reports on ROM status and size. This powerful tool can dissect ROMs down to section level, dissect NVRAM Variables, compare two ROMs and search the GUIDs of a given FFS to provide a summary of their sizes from ROM.
