Compressed BIOS package for a desktop motherboard labelled ZX-I945LM, version 3.2 according to the name, packed as a 533 KB RAR archive. The model code suggests an Intel 945-based micro-ATX board, though the name gives no chip vendor or flash size. Technicians use such an image to recover a board that fails to post after a corrupted update, writing it to the SPI or LPC flash with a programmer. Extract the archive first, compare the image size to the chip capacity, and save a dump of the original chip before writing 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.
