BIOS dump archive for a laptop mainboard numbered DA0ZARMBAI1, revision I, packed as a 10.8 MB RAR. The name gives a 16MB flash size and an OKOK tag, which usually means it was reported as tested and working. DA0 numbers with an MB suffix follow the Quanta board scheme, so the laptop brand itself is not stated. Before writing it with a CH341A or similar SPI programmer, confirm the board number and revision printed on the PCB, read and save the original chip, and check that the image is exactly 16MB.
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 @biosarchive. Enginerys does not host this file.
