BIOS image for the Rowdies design on the Intel Gemini Lake platform, Wistron board 18774-1, packed as RAR. The name also carries the code RXMW5 and gives a 16MB size for the flash. Wistron uses five-digit numbers with a dash suffix like this one. Technicians write such dumps with an SPI programmer to recover machines with corrupted firmware or boot loops. Read out and save the existing chip, confirm the board number on the PCB, and make sure the chip is 16MB before programming.
