BIOS dump for the PLAC_CSAC board, UMA version, revision 2.1, compressed as a 1.38 MB RAR. UMA means the board runs on integrated graphics without a dedicated video chip. It appears to cover the same board as other PLACCSAC 2.1 files, so compare contents if you hold both. Use it to rewrite a corrupted SPI flash with a clip or programmer, but first verify the revision on the PCB, save a backup of the original chip and confirm the image size matches the chip capacity.
