BIOS firmware for the ASRock Z390 Pro4 desktop motherboard, version 4.00, with the name noting support for 8th and 9th generation processors. The 8.40 MB RAR likely holds the update image usable through the board's flash utility or, after a failed update, by writing to the SPI chip with a programmer. Back up the existing chip before reflashing, keep in mind board-specific data such as the MAC address, and confirm the image size matches the flash capacity.
