How to Install and Use ATIflash 2.93 for AMD VBIOS Flashing ATIflash (often referred to as AMDVBFlash in newer versions) is a powerful command-line utility designed to update, backup, or modify the Video BIOS (VBIOS) of AMD Radeon graphics cards. Version 2.93 is particularly popular for flashing Navi-based Radeon RX 5700 series cards.
This guide outlines how to safely install and use ATIflash 2.93 on Windows. ⚠️ Crucial Disclaimer
Flashing your VBIOS carries a risk of bricking your graphics card. This process can result in a black screen, system failure, or a permanently damaged GPU if not done correctly, especially during power failures. Proceed at your own risk. Always backup your original BIOS first. 1. Prerequisites and Preparation
Before starting the installation, ensure you have the following:
Download ATIFlash 2.93: Get the atiflash_293.zip package (ensure it is the 2.93 version specifically for compatibility with older Navi cards).
Download the New VBIOS: Obtain the correct .rom file for your specific graphics card model.
GPU-Z: Recommended to back up your current BIOS before flashing.
Unzip the Files: Extract the contents of atiflash_293.zip to a folder on your computer. 2. Installing/Setting Up ATIFlash 2.93
Unlike typical Windows software, ATIFlash is a portable command-line tool. It does not have a formal installation wizard.
Create a Folder: Create a new folder on your C: drive named atiflash (C:\atiflash).
Move Files: Move the extracted atiflash_293 files (specifically amdvbflash.exe and any supporting files) into C:\atiflash.
Prepare the VBIOS File: Take your downloaded .rom file and rename it to something simple (e.g., new.rom).
Move VBIOS: Move the new.rom file into the C:\atiflash folder. 3. Running ATIFlash 2.93 atiflash 293 install
To flash the VBIOS, you must use the Command Prompt with administrative privileges.
Open Command Prompt: Click the Start menu, type cmd, right-click "Command Prompt" and select "Run as administrator".
Navigate to the Folder: In the command prompt, type the following and press Enter:cd C:\atiflash
Unlock the ROM: Before flashing, unlock the card's ROM. Type the following command and press Enter:amdvbflash.exe -unlockrom 0 (The 0 represents the first GPU). 4. Flashing the VBIOS Once the ROM is unlocked, you can proceed with the flash.
Backup Existing BIOS (Recommended): Type amdvbflash.exe -s 0 backup.rom to save your current BIOS.
Flash the New BIOS: Type the following command and press Enter:amdvbflash.exe -p 0 new.rom(Note: Replace new.rom with the actual name of your BIOS file).
Wait for Completion: Do not interrupt the process. It will show progress and confirm "SUCCESS" when finished. Restart: Once the flash is finished, restart your computer. Troubleshooting & Tips
"Error 0FL01": This usually means the BIOS you are trying to flash is not valid for your card, or you are not running as administrator.
Multiple GPUs: If you have multiple cards, the -i command can list them, and the 0 in -p 0 can be changed to 1, 2, etc., to select the target card.
Driver Uninstaller: It is highly recommended to uninstall your AMD drivers using Display Driver Uninstaller (DDU) before flashing to avoid compatibility issues, and reinstall them afterward.
Dual BIOS: If your card has a physical switch for a dual BIOS, keep one side in the original state to recover from a failed flash.

atiflash -version.To install and use ATIFlash (AMD VBFlash) version 2.93 , follow these steps. Please note that this version is specifically popular for unlocking or modification of certain AMD cards like the RX 5000 series. Prerequisites Backup Your BIOS : Before making any changes, always save your current BIOS. Disable Anti-Virus
: Security software may flag the tool as a threat because it accesses hardware at a low level. Disable the GPU
: To ensure a stable flash, it is recommended to disable your graphics card in the Windows Device Manager (under "Video adapters") before starting the process. Installation & Flashing Steps Extract the Files
: Download ATIFlash 2.93 and extract the contents into a simple folder path, such as C:\293plus Run as Administrator : Right-click the Command Prompt (CMD) and select Run as Administrator Navigate to the Folder : In the CMD window, type cd C:\293plus Unlock the ROM
: Use the following command to allow the card to be flashed: amdvbflash.exe -unlockrom 0 Flash the BIOS
: Once you see the "ROM Unlocked" message, use the flash command (replacing your_bios.rom with your actual file name): amdvbflash.exe -f -p 0 your_bios.rom Download ATIFlash 293: Start by downloading the ATIFlash
: Wait for the "Restart System To Complete VBios Update" message, then reboot your computer. Important Safety Warnings Power Supply
: Ensure your PC is connected to a stable power source. If power is lost during a flash, the GPU may become "bricked" (permanently unusable).
: If your card has a physical BIOS switch, make sure you know which one you are flashing so you have a backup position to boot from if things go wrong. Linux Alternative
: If the Windows version fails, some users recommend using a Linux-based USB bootable version for a more reliable flash. reputable repository to download the specific 2.93 version files?

Technology moves fast, so why do people still hunt for this specific version?
ATIFlash 2.93 struck a perfect balance. It was modern enough to handle the Polaris architecture (RX 470, 480, 570, 580), yet it retained a level of raw access that newer, more "user-friendly" tools sometimes restricted. It was the "Goldilocks" version: stable, compatible, and unforgiving.
It was the version that popularized the "unlock" phenomenon. Certain graphics cards were sold with some of their processing cores locked. Enthusiasts used 2.93 to flash a modified BIOS that would "unlock" these dormant cores, essentially getting $200 worth of performance out of a $150 card. It was a digital treasure hunt, and ATIFlash was the shovel.
As of late 2024 and into 2025, AtiFlash 293 remains the primary tool, but with caveats. For RDNA 3 (RX 7900 XT, etc.), AMD has introduced stricter cryptographic signing on vBIOS. While AtiFlash 293 can read these cards, writing often requires a hardware SPI flasher (like CH341A). If you own an RX 7000 series card, check forum threads specific to your model before using the -f flag.
