Backup dump of the BIOS from an NM70-I board, revision 1.0, read from a Winbond 25Q64FVSIG SPI flash with a capacity of 8 MB, packed in a RAR archive. Because the image comes from that chip type, it should match the 64 Mbit part directly when written with a programmer such as a CH341A or RT809. A backup like this is useful when the original firmware is corrupted and the board stays dead or loops at power-on. Verify the chip marking and board revision on your unit and keep a copy of your own chip before erasing it.
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.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
