Desktop BIOS image referencing a Conroe-era board with the 945 chipset, labelled 5P945C GLI; the exact board maker is not stated. Conroe is Intel's Core 2 Duo desktop core, and 945-series chipsets supported it on many socket 775 boards. The 512 KB size matches a 4 Mbit flash chip, usually SPI or older LPC/FWH parts on boards of this generation. Confirm the chip type your programmer must handle, compare the board model silkscreen, and keep a backup of the original contents before reflashing.
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 @biosbigarchives. Enginerys does not host this file.
