Dell GX240 lockup

We been getting Dell GX240 at work for the past month or so, and installing
QNX for teststation. Only problem is that with the default bios settings
lock up QNX 6.1 during bootup. When I go in and turn off USB emulation it
boots fine and I can install. Apparently USB emulation lets the bios use
USB devices instead of the PS2 style devices. The problem is these come
with MS USB mice, and even though they are suppose to be supported by QNX
the mouse is dead. I have swapped out the mice on every system so far, but
I don’t want to have to trouble shoot every system that comes in. Is there
anything I can do to make setting up these systems less problematic for
other people?
