Zip archive of about 4.02 MB for a board identified as IPM81-SV. Naming of this kind follows the convention used for OEM desktop boards found in brand-name PCs, and the token points to an Intel H81-class platform, though the name gives no revision. Contents are not listed, but the size fits a BIOS dump for an SPI flash chip. Verify the model sticker or silkscreen on the board, read and keep the original firmware with a programmer, and confirm the dump size matches the chip before programming.
