Zipped BIOS dump named 089E8.bin, associated with board DAN18MB48A0, a Quanta ODM board number. The short file name carries no model or revision, so the board code is the main identifier. Extracted, the image should be roughly 8 MB, suited to a 64 Mbit SPI flash chip programmed with a CH341A or similar tool. Match the board number and revision printed on the PCB, read and save the original chip first, and verify the written data after programming.
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 @vinafix_bios. Enginerys does not host this file.
