From your command prompt (Run -> 'cmd'), navigate to your EQEmu directory where your zone.exe is located.
Type 'start zone.exe zoneshortname' (ie, start zone.exe qeytoqrg to boot Qeynos Hills)
And, of course, you can create a batch file to automate the boot up of certain static zones if you like.
To create a batch file, create a new text document inside the Emu directory and edit it to read something like this:
Code:
start world.exe
start zone.exe qeynos
start zone.exe freeporte
start zone.exe cshome
start zone.exe
start zone.exe
Then change the text files extension from .txt to .bat.
This boots up the world, 3 static and 2 dynamic zones.
Of course, you will boot up whichever zones you choose from here. As stated, that particular batch file will boot up an instance of World, as well. This can be useful if you want to boot up the server and all of the zones with one click.
