inputtrap gives wrong command

I am booting photon from diskettes …
running inputtrap on my system, suggests the following cmd line:

devi-hirun kbd fd -d/dev/kbd ps2 kb -2 &

When I run this command, I get:

Open failed: 2
Open failed: 2

And the everything locks up.
I excluded the “kbd fd -d/dev/kbd” pararmeters, and I succesfully
load it and everything else for photon, however in the photon env
the keyboard does not work, I guess becuase I took those params out.

Any help is grealty appreciated,
