BIOS for Wistron board 19723-1 on the XMA1901-YN platform, labelled as fully working and stored in a 5.05 MB RAR. Several dumps for this board exist, so if one fails, an alternative version may suit your unit. The image is written to the SPI flash chip using a hardware programmer to recover a board with corrupt firmware. Wistron uses this numbering style for notebook boards across brands. Back up the original chip, confirm the PCB number, and make sure the file size fits the flash chip.
