There was a good thread on the /r/flying subreddit discussing this procedure yesterday. Specifically, poster /u/veritasiness outlined the entire procedure step by step [1] which I'll cut and paste here:
0:02 ground power turned on. The plane is basically "plugged in" to an outlet. This
turns on the electric systems from that power source.
0:03 cabin / utilities on
0:05 voice recorder check
0:06 turning on (aligning) IRS
0:10 Fire checks (Bell, loop, fault)
0:12 Extinguisher checks (3 bottles)
0:13 Cargo extinguisher checks
0:15 Oxygen mask check (demand only / emergency)
0:20 Audio Selector Panel setup. Buttons on the top are the options for transmitting.
Knobs on second row are options for listening.
0:30 FMS setup (also part of aligning IRS Navs)
0:34 Manual route entry. Left side are the airways (roads) and right side are the
fixes (intersections)
0:40 Arrival Setup. Left side are the STandard ARivals. (STARS) Right side are the
actual runways approaches.
0:44 Fuel pumps on.
0:45 engine driven and electric hydraulic pumps on. Note: several operators leave
the A side off for push back because nose wheel steering is commanded by
A-Side hydraulics. There is also a bypass on the gear as an alternative to
shutting off the A-Side.
0:48 overspeed warning test. (clacker is what goes off if you overspeed the plane
and is an indication of a good check)
0:50 window heat on (1 for each window)
0:52 AC setup
0:54 setting cruise altitude on the pressurization panel
0:55 setting landing altitude
0:58 Flight director on. ("MA" is master. It's the copilot's leg to fly)
1:01 Autobrake to RTO (Rejected Take Off)
1:06 cockpit light check
1:10 transponder to 2 (It's the copilot's leg)
1:19 GPWS check
1:30 Hyd pumps off (see above)
1:31 AC packs off
1:33 beacon on
1:35 pilot cooling fan #2
1:58 ignition switches to ground (starts the engine turning)
2:02 fuel switch on (introduces fuel to the engine). Also how you shut the engine
down.
2:06 N2 rotation - speed at which the engine is turning. Fuel is typically
introduced at 25% N2. Too early / slow and you might get a hung start.
Or a hot start.
