This article was previously published under Q99283

SUMMARY

When troubleshooting problems with Microsoft CD products, you may have to restart your machine using your MS-DOS startup disks (that is, perform a "clean boot"). This procedure helps eliminate possible conflicts with third-party device drivers and other terminate-and-stay-resident (TSR) programs. This article discusses performing this procedure with a CD-ROM drive.

MORE INFORMATION

When performing a "clean boot", you may need to retain access to the computer's CD-ROM drive. The following lines must be retained in the computer's system files:

REQUIRED

   AUTOEXEC.BAT File
   -----------------
   <drive>:\<path>\mscdex.exe <switches>
				
   CONFIG.SYS File
   ---------------

   device=<drive>:\<path>\<cd-rom driver> <switches>
where <drive> represents the drive letter that contains the file, <path> represents the path to the file, <cd-rom driver> represents the filename of the CD-ROM driver and <switches> represents any relevant software switches required by the device.

MAY BE REQUIRED

   CONFIG.SYS File
   ---------------

   device=<drive>:\<path>\setver.exe
where <drive> represents the drive letter that contains the file and <path> represents the path to the file. This line will be needed if the version of Microsoft CD-ROM Extensions (MSCDEX) was written for an earlier version of MS-DOS than is currently installed on the system. 
   device=<drive>:\<path>\smartdrv.exe /double_buffer
where <drive> represents the drive letter that contains the file and <path> represents the path to the file. Some older CD-ROM drives require this entry for Windows to access the drive. For additional information about this entry, query on the following words in the Microsoft Knowledge Base:

In addition, some CD-ROM drives (such a some from Creative Labs) require a batch file to be run at MS-DOS that will install additional switches required for the MSCDEX.
