CQ61 BIOS dump tagged serial in its name, stored as a second copy (2), 1.00 MB, without a file extension. The tag suggests the image still contains a serial number or system identification data, though the name does not specify. Such dumps are useful for restoring identity data after a clean reflash, but writing another machine's serial to a different board is not appropriate. Confirm an 8 Mbit chip is fitted, back up the original contents, and compare data areas with a hex editor.
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 →
