BIOS archive for the Mega PCWare IPM45 desktop motherboard, revision 1.0, with a trailing 1 GA token whose meaning is not certain. The IPM45 label points to an Intel P45 or G45 family board, common in older OEM desktops. The 454 KB ZIP is small, so expect a compact image for an older SPI or LPC chip. Unpack it, compare the image length with the flash chip capacity, and save the original contents before reprogramming, so a failed write can be rolled back.
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.
