Gigabyte BIOS image for a board identified as MZBSWBP, revision 1.0, meant for an 8 MB flash chip and packed into a 3.8 MB RAR. The name gives no model, chipset or firmware version beyond that code, so identify the product by the label on the PCB before use. A file like this lets a technician reprogram the SPI flash directly with a programmer when the board will not POST or a failed update left it unbootable. Confirm the chip capacity really is 8 MB, check the board revision matches 1.0, and save a copy of the current contents before writing.
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 →
