easy question for most i hope

The short shift lever is has 4 positions, not counting neutral:
4 high range (unlocked center diff)- normal position for everyday use in high traction terrain center diff balances drive to the front and rear axle as needed.
4 low range (unlocked center diff) - low range, for slow going or very heavy load, but otherwise same as 4 hi
4 high range lock - locks center diff so same amount of power goes to the front and rear axles. Used for normal speeds on low traction surfaces, like mud, ice, snow.
4 low range lock - same as 4 high lock, but low range like regular 4 low
4 hi lock and 4 low lock must not be used on high traction surfaces otherwise you'll get driveline windup resulting in aggressive tire wear and possible driveline damage.
If you're on a really low traction surface without the center diff locked, 100% of the torque will go to the front or rear axle, whichever one doesn't have any traction and you won't move.

Thanks, but what is odd is it has a small stick with only low/neutral and high. The stick does not have the options you have explained. The previous owner says it has lockers (none visible). And that all 4 wheels are working all the time. Is this possible? Is there after market parts available for this application?

Antichrist.. if I drive 99.9999999 % percent of the time on Chicago city streets and freeways what should I have it in because ever since I purchased my disco its always been in 4x4 and now that I am thinking about it I wonder if it is bad that I left it in 4x4 when I really didn't need to.
The only time I really need 4x4 is during Chicago winters or if it starts to rain really bad.

Coil sprung Land Rovers have full-time 4WD.
When you say it's "always been 4X4" do you mean 4WD lock (there would be a light in the instrument cluster indicating it is, unless it's burned out)? If so, that's bad. For normal driving the transfer lever should be all the way to the right and all the way back.
