BIOS archive for the ZX-H61C motherboard, revision 1.4, 2.56 MB, built around the Intel H61 chipset. Firmware for v1.2 boards differs, so confirm the revision silkscreened on the PCB before flashing. The image is written directly to the SPI flash with an external programmer to revive a dead board. Read and keep the original contents, which include ME data and the network MAC address, and verify the unpacked file matches the flash chip size so it will fit.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @Laptopdesktopbios. Enginerys does not host this file.
