2. Creates an MSCDEX line in your AUTOEXEC.BAT file.
Microsoft CD-ROM Extensions (MSCDEX) is a program that allows a CD-ROM disc to be accessed using DOS commands. It assigns a DOS drive letter to the CD-ROM device, and "interprets" the CD-ROM file format. If you are currently using DOS version 6.0 or later, you will find the file MSCDEX.EXE in your DOS directory. The installation program will add these lines to your AUTOEXEC.BAT file:
rem ---------- MTM ATAPI CD-ROM ---------C:\DOS\MSCDEX.EXE /D:MTMIDE01 /M:10 rem ---------- MTM ATAPI CD-ROM ----------
The middle line tells your computer to find the device that uses the name MTMIDE01 and assign the next available drive letter to it. The drive name must be the same defined in CONFIG.SYS, otherwise the CD-ROM drive will not be found. Do not specify any subdirectory name as a drive name. By doing so, the subdirectory may be damaged. /M:10 is a software switch that tells your computer to reserve 10 buffers in memory for faster CD-ROM access. For more information on MSCDEX parameters, go to the DOS directory and type HELP. Choose MSCDEX from the list of files and press ENTER.
