I found out that iboost is an internal Intel BIOS feature which increases DisplayPort signal strength. Apparently there was some problem with external monitors connected to USB-C dock, and "enable iboost" improves the situation. It is an internal BIOS setting, not anything in BIOS setup or anywhere that end user can change. So I have no idea why they wrote "enable iboost" into the readme rather than simply explaining which problem was fixed in a way that customer (or even support staff) can understand. I have given this feedback to the BIOS team which writes the readme. Sorry for this confusion.

Besides supposedly enabling this "iboost" function, the readme states also this:
- updated Kabylake-R Y-0 MCU to MC0806EA_000000B3_000000B4 and
Kabylake H-0/J-1 MCU to MC0806E9_000000B3_000000B4
- update Diagnostics tool, Version 04.07.003
what does this do or mean?
I'm guessing just like me you are holding on to an earlier BIOS version, because of the crippeling GPU throtteling that was introduced in later versions, and now everyone's eager to understand what changes we miss out

Those items are referring to CPU microcode from Intel (which gets updated frequently), and the built-in diagnostics that you can launch by rebooting and pressing F10 at the Lenovo logo screen.
