BIOS image labelled nc6400n, a name matching the HP Compaq nc6400 business notebook naming, supplied as a 1.00 MB raw binary. The trailing n may denote a variant or a modified copy, but the name gives no further detail on revision or contents. A dump of this size suits an 8 Mbit SPI flash chip and is written with a programmer such as a CH341A or RT809H. Compare the chip capacity with the file size, read and save the original contents first, and verify the write afterwards before reassembling the notebook.
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 @bios_laptop. Enginerys does not host this file.
