BIOS archive for the Compal BDL50 platform, board LA-D704P revision 4.0, in a 5.19 MB RAR. Compal uses LA-prefixed numbers for its motherboards and a short code like BDL50 for the platform shared by related models. A later revision can use different parts than earlier versions, so confirm the board shows rev 4.0 before trusting this dump. Typical use is reprogramming the SPI flash with an external programmer after a failed update or corruption. Save a full read of the original chip first so its serial and system data can be restored.
