 ==== Chapter 3: Writing !Start.bat files ====
- Upon booting, the X68000 executes files from config.sys. Usually they are with X or SYS extension. Those with X approximately 50% of all cases can be executed from autoexec.bat or from command line. There SYS files and some rare X files need ADDDRV, just like in the Namachuukei 68 example. At first I was very excited about ADDDRV because I wanted Nama68 on HDD for a long long time. It turned out that it is incompatible with almost anything I throw at it, but sometimes it does the trick. Best way to find out is by trial and error.

+  * *.X files, which are required for the game to run, in almost all cases can be executed from *.BAT files or command line.
+  * *.SYS files and some rare *.X files need ADDDRV (Example #4). ADDDRV is very picky and most of the times incompatible.
 **Combining lines from Config.sys and Autoexec.bat**
- Now that we know that most files from config.sys with extension X can be executed as standalone, its time to write them in the beginning of autoexec.bat

-Here we can see drivers being loaded and environmental variables being set up. The very important ones and drivers like USKCG.SYS and FLOAT2.X are being set up each time when booting from HDD so most of these can be safely ignored. Most of the times those drivers which will interest us will be loaded from "SYS" and "BIN" directories. In this example OPMDRV3.X and IOCS.X are the ones which interest us. First we must check if they can be executed after the system has fully booted. If yes, then there is a good chance that the game can be installed to HDD.

-Here we can see another environmental variable called "PATH" being set up. In this case we can go with the lazy method and SUBST to the directory where we have copied the game or we can change the paths so that we don't have to do SUBST. Remove references to "A:\", "\" or "B:\" if they are present and after this line write the two commands from config.sys. Rename autoexec.bat to !Start.bat and enjoy the show. The resulting !Start.bat should look like this:
