I had a working installation of OS X on my Vostro A90. I used dellefi to enable two finger scrolling, then disabled it. I then enabled bluetooth, and some time later, shut down my computer. When I restarted it, it was frozen with the bluetooth setup assistant looking for a bluetooth mouse. I disabled bluetooth in the bios, and now on startup it is frozen and does not respond to mouse or keyboard input. I do not have an external keyboard or mouse to plug in to install new drivers (I had read on searching that someone else had suffered a similar problem and solved it by installing a new touchpad driver). Is there anything shy of a reinstall I can do without an external keyboard or mouse?
Thank you for your time and help.
