this is a pre HCI 11.2 firmware and my oldest card is a Xircom CBT one
with build id 101.

No. This is always done separately. However this boot loader shouldn't
check the signature of the DFU file and so in general you can try to
load a HCI 16.4 on it. Of course at your own risk. Does Sony provide an
update for this notebook?

Regards

Marcel
