Firmware for the Dell Inspiron 15 5558 on the Compal LA-B843P motherboard, revision 1.0, carrying the AAL10 platform code. The 4.55 MB ZIP archive is used to recover a laptop that powers on with no display or is stuck after a bad BIOS flash, by writing the image directly to the SPI chip. Programming software such as the CH341A tools or NeoProgrammer opens the extracted binary. Back up the existing contents, then confirm that the file size equals the chip capacity before erasing 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 @biosarchive. Enginerys does not host this file.
