Though it says "IRQ 2" in the INSTALL.EXE, is actually is "IRQ 9" on
probably all PCs >=286 (it's one of the design features of the PC Architecture,
it comes from cascading two interrupt controllers with 8 input lines each)
through exactly this IRQ 2.

And has been working as such successfully with and since the first release
of Xlinux.8514 under 0.97pl6 almost a year ago. I don't know what that
atixlmouse support is for, I've never tried it -- microsoft busmouse is fine.
The only thing you have to remember is to change the IRQ entry in the
include file to match the value you specify in INSTALL and recompile
the kernel. Just remember: when the INSTALL.EXE tells you "IRQ 2",
it really is "IRQ 9":
/usr/include/linux/busmouse.h: #define MOUSE_IRQ 9
