It is presumably just doing an INT 11h and parsing the bits of AX.
I used to assign that as homework to my assembly language classes.
That gave excellent practice with using AND, SHR, etc.
But the switch settings no longer provide reliable info.
Hmmmm. maybe I should assign reading the CMOS and displaying the
information that it represents.
It has one problem though. It is confused as to OFF
and ON!!!
Each of the switches is switched to "open" for "YES". Therefore,
"logical
ON" became "electrical off"
One of the first rounds of IBM's "Guide to Operations" had it backwards
for the setting for the "Math coprocessor present" switch! That resulted
in half of the machines being set wrong.
