BIOS package for the ASUS M1403QA laptop, board revision 2.0, described as fully working and supplied as a 7.75 MB RAR archive. A dump like this lets you recover a laptop that will not boot because of corrupted firmware, by programming the SPI flash directly with a CH341A or a similar programmer. Before flashing, confirm that the board revision on the PCB reads 2.0. Read and archive the existing chip contents, and make sure the extracted image size matches the flash chip.
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.
