Firmware for an N3 mobile laptop with board marking NB93D3-455-LF, revision 1.0, packed in a small 668 KB RAR. The name states no BIOS version, chip type or flash size, so check the contents before writing. A file of this kind is normally used to reprogram the firmware chip with an external programmer when the machine fails to start. Compare the image size to the actual chip, read and keep the original data first, and ensure the board number on the PCB matches exactly.
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 @biosarchive. Enginerys does not host this file.
