RAR archive of 649 KB named for the Eee PC 1002, an ASUS netbook model, although the name does not say whether it holds a schematic, boardview or BIOS image. Open it with WinRAR or 7-Zip and inspect the contents before planning a repair. If it contains firmware, back up the original SPI chip with a programmer first and check that the image size matches the flash capacity; if it is a schematic or layout, confirm the board revision on the PCB matches the document.
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 @ITHINKHS. Enginerys does not host this file.
