Gigabyte GA-Z77-HD4 desktop motherboard archive for PCB revision 1.0, an 813 KB RAR. The size suggests a BIOS image or a compact document, so check the contents after extraction. The Z77 chipset hosts Intel Ivy Bridge and Sandy Bridge CPUs. When reflashing, read and save the original SPI chip first, confirm the image matches the chip size, and note Gigabyte boards may use dual BIOS. Verify the revision printed near the PCIe slots reads 1.0.
