AMDVBFlash / ATI ATIFlash is a utility used to flash the BIOS on AMD graphics cards.
Originally released by ATI as ATIFlash (also known as WinFlash), it supports all AMD Radeon GPUs — from the latest RX 5000/6000/7000 series down to older ATI cards. It’s a simple, powerful tool for updating or modifying your graphics card’s video BIOS.
