Next time, please show, what effort you already put into finding the
right answer yourself. `git log src/mouse.c` and `git grep mouse.c` and
`git grep MOUSE` already shows quite a lot.
```
config MOUSE
bool "Mouse interface"
default y
help
Support for int15c2 mouse calls.
```
Then search for that BIOS interrupt call [1].
So, it’s my understanding, that the BIOS interface allows to control a
mouse pointer using the BIOS interrupt call 15.C2.
Programs and operating systems like Microsoft DOS use that to drive the
mouse.
Kind regards,
Paul
