What is ATIFlash?

ATIFlash - is a small utility used to flash BIOS on GPUs. Able to work only with ATI video cards. The utility supports absolutely all AMD Radeon video cards, including the well-known RX580, RX 6800XT and others. The application works under Windows as well as DOS and Linux.

AMD VBFlash was originally called Atiwinflash. However, after the release of version 2.7.1, it was simply renamed Atiflash. The 274 version was already well known under this name.

Supported video cards:

RX 6900 XT, RX 6800 XT, RX 6700 XT, RX 5700, RX 5600, RX 5500. You can also flash the BIOS for all AMD Radeon RX Vega, RX 580, RX 480, and all older ATI cards.

Tool requirements

  • ATIFlash, a tool for flashing AMD graphics cards.
  • TechPowerUp GPU-Z.
  • An existing BIOS backup file.
  • New BIOS version.

How to Use ATIFlash?

Step 1 - Download the program

Download the program from the official TechPowerUp website. Or download the release from SourceForge. Select the software for the required operating system. atiflash download

Step 2 - Make a BIOS backup

Extract the .zip archive and run amdvbflashWin.exe. Right-click and select "run as administrator."

atiflash admin

Click the "Save" button for the video card selected above.

atiflash_save

A window for selecting a path for saving will open. Enter a name to save. For example original_bios.rom. Or save it as the name of your graphics card. For example: OnginBios.rom.

atiflash_save2

If saving the native BIOS is successful, you will see the inscription "ROM image saved to file". Click "Continue".

Step 3 - Flash the new BIOS

Run the program as administrator and click Load Image.

atiflash_load_image

Make sure to select the correct BIOS and the video card you want to flash. Click Open. By the way, the PolarisBiosEditor program will help you choose the BIOS.

atiflash_open_bios

In the field Filename ou will see the full path to the new BIOS version. Click Program to start the firmware process.

atiflash_gui_program_bios

Wait for the process to go through.

atiflash_progress

If successful, the program will inform you: Your VBIOS was programmed successfully:

atiflash_programm_success

Click OK. You should now do a reboot - You have to reboot this system before the changes take effect. Click "Yes".

atiflash_reboot

Done.

Video Guide

If you see error 43 after flashing, then you need to apply Atikmdag Patcher.

 

 

Let’s consider the second variant of DOS firmware.

The program also works from the command line and in DOS. You can use the .bat file or you can use the CMD.

This option is more complex, but more reliable because the command shell is less likely to crash than the graphical one.

How to flash through the command line (DOS)?

Step 1 - Download the softwareу

Download the program from the official TechPowerUp website. Or download the release from SourceForge. Select the software for the required operating system. atiflash download

Step 2 - Make a backup of the BIOS

Extract the .zip archive. Create two .bat files:

  1. BackupBios.
  2. FlashBIOS.
atiflash_bat

One will be used to create a backup, and the second for the firmware of the new version.

Run BackupBios.batt to keep the original BIOS. Here are the contents of this file:

@echo off
cls

echo Saving bios to BIOS_backup.rom...
echo.
AtiFlash -s 0 BIOS_backup.rom
echo.

pause

If you do not have this file, create it. Copy the text into notepad and give an .txt extension instead .bat

If the file does not start, then first run amdvbflash.exe as administrator.

atiflash3

Do this if you see a window like this: "Due to Microsoft Win8 Enhanced Security Features, this Application requires the user to be in Administrator mode. To Enable this mode, please right click the mouse on the application, then select "Run as Administrator". atiflash_admin_bat

Now start by BackupBios.batt double clicking on it. The folder will appear BIOS_backup.rom.

Step 3 - Flash the BIOS of the video card

Now start by FlashBIOS.bat double clicking on it. Here is the content of the file:

@echo off
cls

echo Flashing card 0 with BIOS.rom...
echo.
AtiFlash -p 0 -f BIOS.rom
echo.

pause

During startup, you will see the following window:

atiflash_cmd

Inscriptions programmed and verified will inform you that everything is OK.

Now the utility will inform you "Restart System To Complete VBIOS Update" - we restart the PC.

BIOS flashing AMD cards with DOS

Not working on windows 10

If the program doesn’t work or doesn’t see your graphics card, try the following steps.

  1. Download the new version of the program.
  2. Use Bootable DOS Drive Method.
Video: Bootable DOS Drive Method.

The program may not work in 10k on a certain system assembly

In this case, use either an earlier version of the 10k build, or sew from Strelec WindowsPE.

It has long been known that GPU makers place certain blocks on performance. When it comes to gaming or mining, the performance indicator should be as close as possible to 100-110%.

Commands

Here we will highlight the most useful commands:

command format:

Atiflash [command] [parameter1] [parameter2] [parameter3] [command]

Observe all spaces. However, command brackets are NOT written).

Alternatives

  • ATI Winflash
  • Программа Flashrom
  • Radeon BIOS Editor (Due to the digital signature requirement on the latest AMD cards, RBE is no longer in active development and will not support the latest graphics cards.

Overview of program features

The utility is freely available free of charge. Supported on Windows XP and higher, up to the latest, tenth.

The utility has two modes of operation: through the command line (CMD) and the graphical shell (GUI). You can use any of the methods to update the BIOS. Before carrying out the procedure, be sure to download the BIOS of the required version for your device.

Do not turn off your computer while updating. Otherwise, a failure in the system will lead to the failure of the GPU. Also Atiflash DOS can keep the current firmware. If you run into problems with the new version of the software, it will help you roll back to the previous version.

The BIOS firmware should be changed for several reasons:

  1. To increase the performance of the video card.
  2. Change voltage parameters with power consumption.
  3. To set up a system for mining cryptocurrency.

The software copes with each of the tasks.

The subtleties of the firmware through the graphical shell

Note that this method is only suitable if there are three GPUs in the system. Not more. Otherwise, the utility is not able to show all subsequent ones. Therefore, in this situation, it is worth using the command line. More about this above.

The video card must not only be displayed in Device Manager, but also fully functional. Otherwise, the AMD driver has blocked the custom BIOS.

If you have several identical AMD video cards in your system , then you need to specify the flashing of all video adapters with the same BIOS. Use the file where the modified BIOS is located (for example, BOIS_mod.rom). The command will look like this:

atiflash.exe-pa BIOS_mod_480.rom.

If you have two different GPUs in your system: R9390 and RX 5700, then run the utility with the key –i. View a list of all displayed graphics adapters. Remember the number of the required video adapter. In the command line, write:

Atiflash.exe -video adapter number

Suppose it has parameter 1. Then the command looks like this:

atiflash.exe –p 1 BOIS-mod_480.rom

Troubleshooting

Error 0fl01.

0fl01

Freezing of the GPU or system when flashing BIOS. When updating the BIOS of the video adapter, you must disable it using the “Device Manager”. Also try restarting your computer.

After completing the BIOS update and restarting the PC, the graphics processor is detected, but does not work. There are manufacturer’s drivers that block the operation of the video adapter with an unsigned BIOS.

If you see the inscription: not found adapter - check the correct operation of the video card in the Device Manager.

Video: Solving the Subsystem ID Mismatch error when flashing the BIOS of a video card, RX 570 580 5700

This video shows how to correctly and easily resolve the Subsystem ID Mismatch error when flashing the BIOS of an AMD based graphics card. There are other methods, more complicated and tricky, but using this method it will be possible to avoid bugs and further problems with the video card.

The subsystem mismatch error indicates the wrong choice of firmware or its size. Then it is worth copying the data through Polaris BIOS Editor to the desired file format.

This problem occurs when you try to flash the BIOS of a video card with a BIOS file from another video card or an incompatible BIOS chip model.
