	//if this is useful, donate to LRv8b23mQSZah7bg16n7tjT5RVDnZtMi4Z
	//you must download atiflash from http://liteshack.com/files/atiflash and put into /usr/local/bin/ dir
	//or try your luck here: https://www.google.com/search?q=atiflash+for+linux

//usage:
	//php flash.php /path/to/bios.rom 035
	//this will flash /path/to/bios.rom gpu 0, 3 and 5.
