BIOS for the ASRock B450 Steel Legend, an AMD AM4 motherboard based on the B450 chipset. No firmware version is given in the name, and the 10.4 MB RAR archive may contain more than one image or a 16 MB dump. Technicians program it onto the SPI chip with a hardware programmer when the board has no display or a failed update, or when a newer CPU needs support. Check the version inside, back up the existing chip before writing, and confirm the image size equals the flash capacity, otherwise it will not fit.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
