Working BIOS dump for the ECS-style board R42IIR, part number 37GR42000-B0 at revision B, marked as fully tested, in a 2.26 MB RAR. No device or brand is named. Use it to reprogram the SPI flash with a hardware programmer when the board has corrupted firmware or will not POST. Note the revision B, which differs from the C schematic; check the part number on the PCB, keep a backup of the original chip and confirm the image size matches the flash chip.
