II.1.2 Installation under MS-DOS or Windows

In principle ASEM-51 doesn't require a fuzzy software installation or configuration. In the simplest case you can copy all files of the package to your working directory, and enjoy the benefits of true plug-and-play compatibility!
On the other hand, an installation of ASEM-51 under MS-DOS is very simple:

• Create a new, empty scratch directory on your harddisk.
• Unpack your ASEM-51 distribution archive into this directory, or copy all files of the ASEM-51 package into it.
• Make the scratch directory default, run the batch file INSTALL.BAT provided, and follow the instructions.

If you don't like anything that is running automatically, or things are not quite clear, ASEM-51 can also be installed manually as follows:

• Create a new directory on your harddisk, e.g. C:\ASEM51.
• Copy all files of the ASEM-51 package into this directory.
• Append it to your PATH statement in file AUTOEXEC.BAT, e.g.
  
        PATH C:\DOS;C:\UTIL;C:\ASEM51
• If this has not already been done while unpacking the distribution archive, create a subdirectory, e.g. C:\ASEM51\MCU, and move all the *.MCU files provided to this subdirectory, for better survey.
• Create another subdirectory, e.g. C:\ASEM51\HTML, and move all the *.HTM, *.GIF and *.JPG files to this subdirectory, respectively. (To read that HTML manual, invoke your web browser and start with file C:\ASEM51\HTML\DOCS.HTM!)
• Optionally define a DOS environment variable ASEM51INC in AUTOEXEC.BAT, to specify a search path for include files, e.g.
  
        SET ASEM51INC=C:\ASEM51\MCU;D:\MICROS\MCS51\INCL
• For a proper operation of the Borland 16-bit DPMI server on computers with more than 16 MB RAM, be sure that EMM386.EXE (included in DOS 5.0 or later) is loaded, and define the environment variable DPMIMEM in AUTOEXEC.BAT as follows:
  
        SET DPMIMEM=MAXMEM 16383
• Reboot your PC.

The installation batch file INSTALL.BAT should work properly on MS-DOS, Windows 3.1x, and Windows 9x systems. It has not yet been tested on other Windows versions. Especially for the NT-based Windows versions NT 4.0, 2000 and XP, a manual installation is recommended.
