BIOS .bin 8.00 MB Shared

An 8.00 MB raw BIOS dump marked for an HP 4540 notebook, presumably the ProBook line, with the name twice flagged OK, suggesting it was tested and working. A binary of this size is meant for a matching 8 MB (64 Mbit) SPI flash and is written with a programmer such as a CH341A or RT809. Before flashing, read and store the existing chip, verify the board revision matches yours, and expect that serial, MAC or Windows key data may differ from the donor machine and need correcting afterwards.

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 @biosbigarchives. Enginerys does not host this file.
