BIOS dump for the MSI Pro 22ET 7M-059RU all-in-one PC, board MS-AC171 version 1.0, which the name says was tested and working (teste OK). The archive is a 4.93 MB RAR. A verified image is handy for recovering an AIO that shows no display or keeps rebooting after firmware damage, written to the SPI chip with a programmer. Before you flash, compare the MS-AC171 code and version on the PCB, back up the current contents, and confirm the image size matches the chip installed on the board.
