Compact RAR archive of 572 KB for a Philco 10B device with board number 71R-B11E14-T820 (placa means board). The name does not list the contents, and the small size suggests a firmware dump or short document rather than a full schematic set. The 71R numbering appears on boards from Chinese ODMs used in budget notebooks and tablets. Unpack it with WinRAR or 7-Zip, and if it holds a BIOS image, back up the original chip and check the image size against the flash chip before programming.
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 @oficinacomputadores. Enginerys does not host this file.
