BIOS package for the ASUS UX393E board revision 2.0, version V313, containing both a 1 MB and a 16 MB image according to the name, likely an EC firmware file plus the main SPI BIOS. The 9.65 MB RAR should be extracted and each file matched to the right chip by capacity. Use an SPI programmer such as a CH341A, reading and saving the original contents before writing. An image whose size does not match the flash chip will not fit, so check part markings.
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.
How to open a .rar file
Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
