BIOS image for the Intel D945GZCC desktop motherboard, apparently a second copy as the name suffix suggests, with no file extension. The 512 KB size matches a 4 Mbit flash chip. Intel desktop boards of the 945 generation often used LPC or FWH flash rather than SPI, so check the chip type and programmer support before writing. Compare this copy with other dumps for the same board, read and save the original chip, and use the image to recover a board that no longer posts.
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.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
