Tested BIOS for the ASUS PRIME B250M-C desktop motherboard, firmware version 1608, prepared for an 8MB flash chip. A ready image like this helps when the board stays dead, shows no display or fails after an interrupted update and the chip must be rewritten with a programmer. ASUS desktop boards often use a removable socketed flash chip, which simplifies programming. Save the original content before flashing, as it may hold the MAC address and serial, and confirm the chip is 8MB.
