BIOS archive for the ASUS PRIME B250M-A desktop motherboard, revision 1.02 as stated in the name, packed as a 15.7 MB RAR. The B250 chipset belongs to Intel's 200-series platform, so the image is meant for the board's SPI flash chip. Technicians use such a dump to recover a board that will not POST after a failed update or corrupted firmware, writing it with a CH341A or similar programmer. Confirm the PCB revision silkscreen matches, and read and save the original chip contents before erasing anything.
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 @biosarchive. Enginerys does not host this file.
