New Operating System
CD-ROM Support Under MS-DOS
When installing an operating system on an empty hard disk drive, a DOS real-mode CD-ROM
driver needs to be loaded in the CONFIG.SYS and AUTOEXEC.BAT files in order to use the CD-
ROM drive. The floppy disk drive can be used without any device drivers. PCMCIA cards are not
recommended under DOS but, if necessary, you may consult your PCMCIA card documentation or
dealer for configuration under the DOS environment. The CD-ROM device driver should be pre-
configured from the factory as follows (because hardware and software are constantly improved or
customized for a particular market, the examples in the software section may not exactly reflect
your Notebook PC.
CONFIG.SYS: DEVICE=C:\CDROMDRV.SYS /D:0EMCD001
AUTOEXEC.BAT: MSCDEX.EXE /D:OEMCD001 /L:D
Microsoft Windows 98
Microsoft Windows 98 may be pre-installed on your Notebook PC. If installation or configuration
changes are necessary, please refer to the documentation provided with the Windows 98 operating
system. Once Windows 98 is running, you should use the Windows 98 CD-ROM device driver
instead of the DOS real-mode CD-ROM driver. A DOS driver has poor performance, poor memory
management, and may cause conflicts with other devices.
Removing the DOS real-mode CD-ROM driver
Removing the device line or adding “REM” (upper or lower case) in front of the line will disable the
DOS driver and allow Windows 98 to use its own CD-ROM device driver. Windows 98 may
already add the letters “REM” in front of the DOS CD-ROM drivers in AUTOEXEC.BAT such as:
CONFIG.SYS: rem - By Windows Setup - DEVICE=C:\CDROMDRV.SYS /D:0EMCD001
AUTOEXEC.BAT: rem - By Windows Setup - MSCDEX.EXE /D:OEMCD001 /L:D
If running Windows 98 setup, it will automatically check for real-mode drivers and guide you using
a wizard to remove undetected ones. If these two lines exist and do not have “REM” in front, add
them yourself by opening the files with NOTEPAD.EXE provided by Windows or EDIT.COM
provide by DOS or you may simply delete these two lines.
