Working BIOS image for a board named IS6XM, revision 1.0, sized for a 16 MB flash chip. No brand is given in the name, although IS6XM boards are often found in Lenovo desktops. The dump is labelled as fully working. Use a hardware SPI programmer to write it when the system shows no display or will not post after a failed update. Read and keep the original chip contents first, and confirm the flash capacity is 16 MB.
