Working BIOS for a board code-named CRESCENT, part number 6050A3022501 with MB-A01 suffix, packed in an 18.5 MB RAR. The 6050A pattern is the Inventec numbering scheme, seen on boards built for HP and other brands, though no brand is stated here. Use the image to reprogram the SPI flash with an external programmer when the system will not post. Confirm the full part number and A01 revision on the PCB, keep a backup of the original chip, and check that the image size fits it.
