BIOS package for board code 71R-H14BT4, variant T850, a close relative of the T830 file with the same base code. The name gives no brand, model or chip details. At 6.29 MB the RAR is about twice the size of the T830 archive, which may mean a larger flash or additional files, so check its contents. Use it to reflash the SPI chip with a programmer, after matching the suffix on the PCB label, backing up the original chip and verifying the image fits the flash size.
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.
