can someone say me how to update the µcode of the cpu with xen?

I have added the ucode=scan parameter to xen but it does not seem to work...

the µcode version of my xeon is really old :/

model name    : Intel(R) Xeon(R) CPU E3-1271 v3 @ 3.60GHz
microcode    : 0x10

We use ucode=-1 and provide it as a module for grub.
