Dell Inspiron 5458 BIOS image for the Compal LA-B843P board at revision 1.0, with the AAL10 platform tag noted in the name. The 4.57 MB RAR archive contains the firmware a repair bench writes to the board's SPI chip using a clip or by desoldering the chip. Compal LA-series numbers are often shared across 14- and 15-inch Dell models, so the same image may circulate under different labels. Match the board number and revision, and dump the original chip first so it can be restored.
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 @biosarchive. Enginerys does not host this file.
