RAR archive for the Lenovo E40-70 on Compal board LA-B091P, revision 1.0, about converting a board with discrete graphics to UMA, meaning integrated graphics only. This kind of mod is usually done when the dedicated GPU fails. It typically involves changing strap resistors and the BIOS so the system boots on the integrated graphics. Unpack it with WinRAR or 7-Zip and study the contents before you start. Check that the board number and revision match, and keep a backup of the original BIOS chip contents.
