BIOS archive for a Microsoft Surface identified as model 1724, board X911788-009, delivered as a 5.63 MB RAR file. Model 1724 corresponds to the Surface Pro 4, and the same X911788-009 board appears in a schematic set for that tablet. Firmware dumps like this are written to the SPI flash with a programmer when the device will not boot or is stuck on the logo. Unpack it, check the image size against the chip and save the original read first, since device-specific data is stored there.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
