Duplicate DM4I BIOS dump, 4.00 MB raw .bin; the (2) indicates an extra copy, not a separate revision. The name states no motherboard number, chipset or firmware version. A 32 Mbit SPI flash is the matching target for this size. Technicians often keep two reads of the same chip so they can compare them and catch a faulty dump before flashing. Keep a backup of the chip already on the board, check its capacity, and confirm the board number printed on the PCB matches the source machine.
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.
