To install FireServ, unpack all of the files in the full install rar file
and put them in your mIRC directory.  The files need to be in the same directory
as your mIRC executable file.  (mirc.exe)   These are the files that should be 
there. 

fireserv1.ini 
fireserv2.ini 
fireserva.ini 
fireserv.mrc 

Once these files are in that directory, open mIRC and type 
"/load -rs fireserv.mrc"  
This will start the setup procedure.  Setup will tell you when it is done, 
and what to do when it is done. (Remember, FireServ needs to be installed on 
mIRC version 5.72 or higher.)
