Firmware dump for the compact Dell Latitude E6230, whose board is the Compal LA-7731P, provided as a 286 KB zip with a CD3301 prefix in the name. The LA-xxxxP code follows Compal's numbering scheme for boards produced on Dell's behalf. A dump like this serves to restore a corrupted BIOS or EC area by programming the SPI chip directly. Compare the board marking with LA-7731P, back up the original chip before any write, and check that the file size matches the flash device.
