It is indeed a pin option in the software like Avioniker said above. In a simulator, the change is made by pressing a button when the cockpit is powered off.
Boeing promo material (brochures, pamphlets) and like IfixPlanes said, states it is changed by a software loaded disk. So there might be two ways to change the format. In any case..
There are two pages available on the lower EICAS screen that can be viewed when an aircraft has the PFD/ND (777 style) format. Each page is activated by pressing the ENG or SYS button located by the autobrakes switch. In aircraft using the EFIS/MAP (classic EADI/EHSI) format the buttons are marked INOP and the lower EICAS screen is blank.
In setup 2 IfixPlanes' picture shows the PFD/ND setup. The screen on the right is the lower EICAS ENG page. Picture below is the SYS page which shows flight control surface positions and hydraulic fluid quantity and pressure:
Boeing also has a few optionals for operators on the PFD style screen - VOR in localizer display, show groundspeed (under the airspeed tape), Angle of Attack (to the right of FD
and below G/S), and a Rising Runway display (green rectangles just below the horizon on 5 degrees).
Picture displayed is a PFD setup in a single channel autopilot approach. A dual coupled autoland would have displayed FLARE under G/S.IKOA is the current ILS selected 174 degrees localizer heading/DME
at 1.9 (note both radios are selected at IKOA, with one it would be crossed out). At the top in green, RETARD, VOR/LOC, and G/S (glideslope) are displaying the current mode in the autopilot FMA - flight mode annunciator. RETARD is in the THRUST mode selection, VOR/LOC is in the ROLL mode selection, and G/S is in the PITCH mode selection. FD
is showing the flight director is active. 26 is the radio altimeter altitude in feet. RADIO 200 showing minimums/decision height using radio altimeter. Tape on the left is airspeed, 131 autothrottle speed selected, REF speed is just under 130kts (seems like 131 is +5 for wind correction). Tape on the right showing MSL altitude with 29.98 as the barometric pressure. Far right tape is the vertical speed tape/ needle. Bottom, HSI compass style display with 130 autopilot heading in magenta. Meters for altitude can also be displayed pressing MTRS button located on the display control panel.
Some airlines using EFIS/MAP (classic/EADI/EHSI):
Air Berlin, Air Europa, Continental, Southwest, Varig
/ND (777 style): American, Delta, Lauda, Qantas, VirginBlue
