Firmware image for a 450 G1 labelled GRAPHICS, second copy, 8.00 MB with no extension. The label most likely indicates the board version with a dedicated graphics chip, though the name gives no brand, GPU model or board number. Discrete and integrated graphics boards often use different BIOS images, so confirm which version you have before flashing. Read the original 64 Mbit SPI chip with a programmer and save it, then write the image and verify it by reading it back.
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 →
