BIOS firmware for the Acer Aspire XC-780 desktop, based on the Wistron board 16502-1 with project name Soniah_2. Wistron applies this five-digit dash-revision numbering to boards it builds for Acer and other brands, so compare the code on your motherboard. The archive is 4.79 MB compressed. Use it to recover a dead or corrupt BIOS by programming the SPI flash externally, after saving the original chip contents and confirming the image size matches the flash capacity.
