A 4 MB BIOS image for the Dell E6230 laptop, Compal mainboard LA-7731P, taken from flash position U53. This is the smaller of the two SPI chips on this design and must be used together with the matching U52 dump for a complete firmware restore. LA-xxxxP is the Compal board numbering pattern. Program it with a CH341A or similar tool onto a 4 MB chip only, since a size mismatch will not fit, and read out the original contents before overwriting anything.
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 @biosdumpcomputer. Enginerys does not host this file.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
