BIOS package for the MSI U180 netbook, whose mainboard is listed as MS-N0821, version 1.1, packed in a RAR archive of about 999 KB. The name does not say whether it holds a raw chip dump or a vendor update, so inspect the contents after extracting. A raw image is normally written to the SPI flash with a programmer such as a CH341A when the original firmware is corrupt. Read and save the existing chip contents first, and confirm the image size matches the flash capacity 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.
