Small 66 KB RAR archive for the Sony SE1+ with board MBX-110 at version 2.0, the type listed as a general archive with no further detail on its contents. MBX-xxx is Sony's internal motherboard numbering for VAIO notebooks. Given its size, it likely holds documentation or a small data file rather than a full BIOS image, so open it and check the contents before use. Make sure the MBX number on your board matches before applying anything inside.
