Installation and System Requirement



System Requirements

     The FHM runs on a IBM PC compatible computer.  The processor must be at least a 386. 

The computer must have at least 4 megabytes of memory and 8 megabytes of hard disk space. 

The computer will require more hard disk space for the data sets.  The project data sets can

consume large amounts of disk space (10-100 megabytes).  The FHM will run in DOS, Windows

3.1, or Windows 95.



Installation

     The standard installation for the FHM will create a single directory c:\FHM.  This

directory will contain all the executable codes and support files for the FHM.  It will also contain

the FHMPROJ directory.  This project directory will contain a sample project and eventually all

user created projects (projects are simply sub-directories in which all data files pertaining to the

selected project can be found).



Software Installation

     To install the FHM from floppy diskettes simply go to the DOS prompt and type the

following commands (the FHM can be obtained via FTP, skip the steps below if you already

have the FHM.EXE self extracting file):



     md fhmtemp

     cd fhmtemp

     a:pkunzip a:fhm



Note: The floppy drive to install from is assumed to be the a: drive (this may be the b: drive on

your particular system).  You should be prompted for the different install disks as necessary.



To extract the files using the standard directory structure enter the following command:



     fhm -d c:\



After all the files have been installed successfully, you can delete the temporary installation file

by typing the following commands:



     del fhm.exe

     cd ..

     rm fhmtmp



SYSTEM CONFIGURATION

     AUTOEXEC.BAT

     Next you will need to modify the AUTOEXEC.BAT and CONFIG.SYS files  (it is

recommended to make backup copies of these files before you modify them using the copy

command: copy autoexec.bat autoexec.bak).  To modify these files use an ASCII editor such as

DOS EDIT (you can use a word processor to make the required modifications but, be sure to

save the file as a DOS text file).  To the AUTOEXEC.BAT add the following line:



set path=c:\fhm;%path%



This will add the new FHM directory to your path variable.  This line must be added before any

calls to programs such as Windows (win), Xtree Gold, or Norton Commander.



     CONFIG.SYS

     To the CONFIG.SYS add the following line:



device=c:\dos\ansi.sys



where c:\dos is your DOS directory (note for WINDOWS 95 this directory is typically

c:\windows\command).  This adds a display driver for HSPF displays.



     SYSTEM.INI (for Windows users only)

     For windows machines, the system configuration file must be modified to include

extended memory drivers for the model to run.  Edit the SYSTEM.INI file (this file is located in

the windows directory).  Add the following lines in the 386enh section of the SYSTEM.INI file:



device=C:\FHM\dosxnt.386

device=C:\FHM\mmd.386



Where c:\fhm is the directory that the FHM was installed.



     System Restart

     After all these steps have been followed reboot the computer to activate the changes. 

After restarting the machine type FHM at the command line and the FHM interface will be

displayed.
