BIOS dump covering the NB520 and NB500, second copy, 1.01 MB in .rom format. These look like Toshiba netbook model names, but the name does not state the brand or the board number. The slightly odd size, just over 1 MB, suggests the file may include a header or padding. Check it against the flash chip capacity before programming, because an image that does not match the chip size will not fit cleanly. Verify the board matches, and back up the original contents with your programmer before writing anything.
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.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
