I think there's an error of translation here. The parts I think you're asking about are called inductors.
I have a standard P2B that has had some parts removed and I recall the inductance value was marked on the board underneath. I'm not at home so I can't find it right now, but it looks like the same uH markings are in the photo (not legible in the picture). The color of the inductor also has some significance.

Choke/throttle near enough

Translation is never perfect.

Here's one of the original BOMs
The Inductors should be labelled with L##
Use notepad

Greetings all, perhaps someone has the information I need on this motherboard. I found this board with missing 4 throttles and I really would like to restore it, I don't know for what reason the throttles were removed but I can't find any information on nominal values and parameters of the throttles so that I can pick up modern analogs, as the board is quite rare and expensive I can hardly find a donor.
Can you please advise me of any resources where I could find datasheets for this board, or can you tell me which throttles I need, I would be incredibly grateful.

L13 - near top right corner - 7uH
L17 - 20uH
L12 - 10uH
(unmarked?) - right after the mosfet next to L12 - 4uH

Had the values from a similarly missing-coils P2B-S that doesn't seem to work. I didn't bother fixing that one as I got a working one not long after.

Only one inductor is needed to operate the S370 motherboard.
Its rating is 1-3 µH with a current of about 30 amperes.
It is only needed for the DC-DC regulator for the CPU.
The voltage converter from 5V to 3.3V is an artifact from AT motherboards, it is often excluded for stable operation.
When turned on this way, the motherboard should start if it is not critically damaged.
