Description
BIOS dump for the Dell JH291 laptop, supplied as a BIN file under the original name Dell_JH291_Sharp LQ170M1LA2A DELL INSPIRION PP05XB 1920_1200.bin. The file name mentions a Sharp LQ170M1LA2A display and a PP05XB model reference, but the facts here do not confirm a board number, revision, chip size or any cleaned ME region, so check those against your own board before use. Technicians use a BIOS dump like this to reprogram the SPI flash chip with a programmer after a corrupted BIOS or a failed update.

Questions about this file
How do I flash this BIOS dump?
Write it to the SPI flash chip with a programmer such as the CH341A and a SOIC8 clip. Read and keep the original contents first, and check that the chip size matches the dump.
Will this BIOS work on my board?
Only if the board number and revision match: Dell JH291. Dumps from a different board or revision can leave the board dead.
What does “clean ME” mean?
The Intel ME region in the dump has been reset, so it can be used on another board of the same model. Keep your original dump and transfer serial numbers if needed.
