PS/2 mouse

Hi!

I need to read a PS/2 bus mouse directly, not via INT 33h. Anyone out there
who have any info?

The PS/2 mouse is basically controlled / interrogated by the
INT 15H  AH=0C2H
bios calls. To check for availability use the INT 11H bios call, I
remember it must be bit $04.

Look in Ralph Brown's interrupt tables, a link is in the TP-links URL
in chapter "Information". I suggest you use the html link.

I do not suggest to use direct IO instructions.
