RAR archive for a Dell 1458 laptop, the Inspiron 14R family, labelled for the Core i3 version with ATI discrete graphics. The name does not list the contents, but at 1.76 MB it most likely holds a firmware dump or similar service data; extract it with WinRAR or 7-Zip and inspect before use. If it contains a BIOS image, compare its size with the SPI chip on your board, back up the original chip with a programmer, and confirm the board matches the i3 plus ATI configuration.
