BIOS 8.00 MB Shared

Duplicate copy of a firmware dump for the HP ProBook 4340s, an 8 MB image without file extension or additional notes. Nothing in the name reveals the BIOS version, ME condition or whether it was tested. The size corresponds to a 64 Mbit SPI flash chip. It serves for restoring a board whose BIOS is corrupted, written with a CH341A or similar programmer. Back up the original contents, which hold the serial and product data, and verify the motherboard is from a 4340s before writing.

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 @biosfilebins. Enginerys does not host this file.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
