The OP's BIOS is too old a version to be updated from the download site. From the "Important Information":
"If BIOS version of the machine is older than 29CN26WW (V2.03), please turn to local Lenovo service provider for BIOS update."
I believe the OP is asking if there is any way to update without going through service.
