An 8.00 MB BIOS dump for a 450 G1 marked GRAPHICS, without file extension, apparently meant for the variant fitted with separate graphics; no brand, GPU type or motherboard number appears in the name. The size fits a 64 Mbit flash chip. Technicians write such raw images to repair boards with corrupted firmware. Check the PCB board number and whether a discrete GPU is actually present, back up the existing chip contents and verify after programming.
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 @biosfilebins. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
