Video BIOS for a Sapphire Radeon HD4830 graphics card, packed in an 85.6 KB ZIP archive. The name gives no revision, memory type or board code, so compare the card's PCB, memory vendor and device ID with the image before flashing. A file like this restores a card whose VBIOS got corrupted after a bad update, either with a flashing tool such as ATIFlash or by writing the small SPI chip on the card with a programmer. Always save the original contents first so the card can be reverted if the new image misbehaves.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
