Narrative:

During taxi out on ramp heading sbound; our FMS screen partially failed. I asked the ramp if we could park the aircraft where we were and contact maintenance for a minor problem. I contacted maintenance about the faulty FMS screen and was told to pull 3 circuit breakers by maintenance control. As soon as we pulled the 3 circuit breakers; the first officer and myself detected the smell of smoke in the cockpit. We determined that it was coming from the gaspers. After conferring with each other that we both did indeed smell smoke; I instructed the first officer to pull out the emergency evacuate/evacuation checklist. I contacted the ramp controller; told him we had smoke in the cockpit; we were evacing the passenger; and to call for help. I then called the flight attendant who answered with; 'we have a problem don't we?' I told her to open the main door and evacuate/evacuation the passenger because there was smoke in the cockpit. The flight attendant and some passenger seated near her jumpseat could also smell smoke in the cabin. The first officer and I completed the evacuate/evacuation checklist and exited the airplane after the passenger were removed. The passenger all remained close to the aircraft; forward of the left wing. Airport operations; fire department; and maintenance were at the airplane within a few mins. I used my cell phone and contacted our dispatcher; chief pilots; mr X and mr Y and union to inform them of the situation. A bus was brought out to shuttle the passenger back to the terminal with their personal belongings. Another aircraft was dispatched for our flight; and we completed it approximately 2:15 later. Maintenance determined that the left pack had failed and burned up; sending smoke into the aircraft.
