8 MB BIOS backup for Wistron board 19861-1; the extra vvv token in the name carries no clear meaning. A companion 16 MB backup exists for the same board, so this image probably belongs to a smaller second flash chip or a different variant, which you should establish before programming. Wistron numbers boards with a project code and revision suffix. Use an SPI programmer, confirm the chip is 64 Mbit, store a copy of the original data and verify the write to avoid bricking the board further.

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