Help for ThinkPad X201 update CPU Microcode


I plan to upgrade microcode in old Lenovo ThinkPad X201 BIOS because Lenovo will not release any more new BIOS and I am trying to udate the CPU microcode if it possible.My CPU ID is 20655.I created an empty document text and changing the name to NCPUCODE.BIN and than tried to use cbrom155.exe to erase ALL the microcodes but I got a “Not enough space error”,help would be welcome thanks
