Gigabyte GA-H77TN desktop motherboard BIOS for PCB revision 1.1, packed into a 4.64 MB RAR archive. The H77 in the model name refers to Intel's H77 chipset, and this thin mini-ITX board is often found in all-in-one and compact systems. A technician writes the image to the SPI flash with a programmer when the board shows no display or is stuck in a boot loop. Gigabyte revisions can use different firmware, so confirm 1.1 on the PCB, and back up the original chip before overwriting it.
