BIOS firmware for a motherboard named ZX-H61C, version 2.3, packed in a 2.53 MB ZIP file. The name suggests an H61-based desktop board but states no brand, and it is not clear whether V2.3 is the PCB revision or the BIOS version. Use it to rewrite a corrupted SPI flash chip with an external programmer when the board has no POST or video. Compare the model and version printed on the board, back up the existing chip before erasing it, and check that the image size equals the flash capacity.
