BIOS image for the ZX-H61C motherboard, version 2.3, sized for a 4 MB SPI flash chip. The H61 in the name points to the Intel H61 chipset used with 2nd and 3rd generation Core processors, a platform common on budget and generic boards. Use an SPI programmer to restore a corrupted BIOS, after confirming the chip is 4 MB (32 Mbit) and saving its original contents. Make sure the board revision matches, because a dump for a different version may not boot.
