Why is hardware reserved (too much)?

Question

Computers

Immediately on the move:
OS: Linux amd64 (kali, ubuntu) and Win10 Pro x64
(until the hornbeam restored)
BIOS: Legacy AMI BIOS
Given:
msconfig unchecked The BIOS does not see
the working
bars, but Windows sees
Max. RAM: 16GB (set and more, reserved)
Find:
Where do 2GB (at 10GB), 6GB (at 16GB), 10GB (at 18GB) go?
ASUS M4A89GTD PRO/USB3
AMD Athlon II X3 455
AMD Radeon HD 5700 Series
What is this gypsy magic?
In my opinion, so many GB for the OS just suffocate

Answer 1

Just experimented with setting the bars
