Zipped firmware for the MSI Z77A-GD55 motherboard, MS-7751, at board revision 1.1, about 5.5 MB. MSI uses the MS-xxxx numbering for its own boards, and the revision printed near the PCI slots or board edge should read 1.1 before using this file. Technicians use it to recover a dead board by flashing the SPI chip with a programmer instead of the built-in update tool. Save the original chip contents before writing and check that the image matches the chip capacity.
