Firmware archive for an Acer desktop board identified as IPIMB-AR, with r1.02 most likely the board or BIOS revision; the name does not state the system model. Acer desktop boards with such codes are usually produced by outside manufacturers, so the PCB label is the best guide for matching. Use the dump to reprogram the SPI flash with a programmer when the firmware is corrupted. Read and save the existing chip contents before writing, and check that the image size fits the flash part.
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.
