Working BIOS for a board identified as Princeton, revision A, with the code BID08526. The name gives no brand or device model, so match the code and revision against markings on the motherboard before use. A dump like this is normally written to the SPI flash chip using a hardware programmer to recover a board with damaged firmware. Read and keep the original chip contents first, and check that the 5.98 MB archive holds an image that matches the chip size.
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.
