BIOS for the ASUS M5A78L-M LX/BR desktop motherboard, firmware version 1101, compressed into a 787 KB RAR. Being a retail ASUS board rather than an ODM laptop design, its BIOS can usually be updated through the built-in utility while the system still boots, or written externally to the SPI chip when it does not. Confirm the exact board variant, since LX and other suffixes differ, save the existing chip contents before flashing, and check that the image size suits the installed flash part.
