Third copy of a 4.00 MB BIOS image named 650hp C, apparently linked to an HP 650 laptop, with no motherboard number or version included. The meaning of the letter C is not explained by the name. Identical reads across copies indicate a reliable dump, while differences suggest a bad clip contact. It can be written to a 32 Mbit SPI chip with a CH341A or similar programmer. Save the existing chip contents first and confirm the board matches before flashing.
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 →
