Video BIOS file in a ZIP archive, about 945 KB, for a graphics chip identified as GN21-X4-A1, with W25Q16FW1 named as the flash chip. The W25Q16FW is a Winbond 16 Mbit (2 MB) 1.8 V SPI flash, so an adapter for low voltage is needed when programming it. A VBIOS dump like this is used to restore a GPU ROM that is corrupted or blank. Back up the original chip before writing, and confirm the GPU and board match before relying on the image.
