DOCUMENT:Q99283 19-FEB-2002 [winmisc] TITLE :Clean Boot Procedure with CD-ROM Drive PRODUCT :Miscellaneous Windows Products PROD/VER: OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows Sound System, versions 1.0, 1.1 ------------------------------------------------------------------------------- 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 ----------------- :\\mscdex.exe CONFIG.SYS File --------------- device=:\\ where represents the drive letter that contains the file, represents the path to the file, represents the filename of the CD-ROM driver and represents any relevant software switches required by the device. MAY BE REQUIRED --------------- CONFIG.SYS File --------------- device=:\\setver.exe where represents the drive letter that contains the file and 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=:\\smartdrv.exe /double_buffer where represents the drive letter that contains the file and 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: troubleshooting and smartdrive and cd-rom abd emm386.exe and noems 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.
