+# amdvbflash
+
+AMD vBIOS flash utility for Linux.
+
+---
+
+This tool can be used to flash or dump the AMD graphics card vBIOS.
+Before AMD acquired the company ATI this tool was also known as `atiflash`.
+
+## Usage
+
+Before flashing a new vBIOS you should dump your vBIOS first.
+For this you need the adapter number of your card.
+The following command will display information of all AMD adapters in the system.
+
+```sh
+sudo ./amdvbflash -i
+```
+
+If you have only one card installed the adapter number will probably be `0`.
+Next we will do a backup of our vBIOS. Where `0` is the adapter number and `<file>` the name of your backup.
+
+```sh
+sudo ./amdvbflash -s 0 <file>
+```
+
+Now we can flash the new vBIOS to our card.
+The following commands will write the vBIOS image in file `<file>` to flash ROM in adapter `0`. Notice that the `-f` option is not support in external versions.
+
+```sh
+sudo ./amdvbflash -f -p 0 <file>
+```
+
+You must reboot your system now.
+
+## Help
+
+This will show you all possible commands and options that are available.
+
+```sh
+sudo ./amdvbflash -h
+```
+
+## Contributing
+
+Our goal is to reverse engineer the flash utility. For this reason any help is welcome.
