Known-good BIOS dump for the ASUS UX303LN laptop, mainboard revision 2.1, marked as fully working. The archive is a 13.7 MB RAR, so unpack it and check which images it contains before flashing. Technicians use such a dump to recover a board that will not post, has a corrupted SPI chip or loops on boot. Confirm that the PCB reads UX303LN rev 2.1, read and save the original chip contents first, and make sure the image size equals the capacity of the flash chip fitted.
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.
