Working BIOS image for a board identified as PW-945GCL, read from an MX25L8005 SPI flash chip, packed as a 404 KB RAR. The 945GCL name suggests a design based on the Intel 945GC chipset, though the name gives no brand. The MX25L8005 is an 8 Mbit (1 MB) Macronix part, so the image should be exactly 1 MB to fit. Program it with an external SPI programmer, save the original chip contents first, and confirm the board marking matches before flashing.
