Working BIOS dump for the Acer Aspire XC-780 desktop, board Soniah_2 with number 16502-1. That number style matches Wistron, the ODM that builds many Acer systems. The RAR holds an image meant to be written straight to the board's SPI flash with a hardware programmer, for example to recover a unit that no longer reaches POST after a failed update. Read and keep the original chip contents first, check the board label matches, and make sure the image size equals the chip capacity.
