Q552UB

BIOS .bin 8.00 MB Shared

BIOS firmware for an ASUS Q552UB notebook in the form of an 8 MB binary image. The name identifies only the model; it does not mention a board revision, BIOS version or whether the ME region has been cleaned. An 8 MB file fits a 64 Mbit SPI chip and is normally written with an external programmer clip or after desoldering. Before programming, read the existing chip twice and compare the copies, keep that backup, and confirm the board model printed on the PCB matches.

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 @efibios. Enginerys does not host this file.
