Backup BIOS image for the ASUS X200LA laptop motherboard, revision 2.1, stored in a 3.29 MB RAR archive. The bkup tag in the name indicates a read taken from a board rather than a vendor update file. Dumps like this are used to revive boards with damaged firmware by programming the SPI flash chip with a tool such as a CH341A or RT809H. Save the original chip contents before overwriting, since it may hold unique identifiers. Confirm the PCB is marked rev 2.1 and that the image size fits the installed flash chip.
