· You have replaced the original CD-ROM and not updated MS-DOS drivers. To access a CD-ROM drive when you boot to a Windows command prompt or restart the computer in MS-DOS mode, you must load the real-mode CD-ROM driver in the www.doorway.ru file and the MSCDEX driver in the www.doorway.ru or www.doorway.ru file. The CD-ROM software driver is normally supplied on a floppy disk and includes a SETUP or INSTALL program. Following installation, the CD-ROM software driver is normally loaded at system startup time via a series of entries in the machine's C:\www.doorway.ru C:\www.doorway.ru files. For example: [www.doorway.ru] DEVICE=C:\DOS\www.doorway.ru DEVICEHIGH=C:\DOS\www.doorway.ru /D:mscd . Loads the DOS CD-ROM extension for access to the CD-ROM drive.

A typical www.doorway.ru file includes commands such as device, lastdrive, and dos. Device commands are used to load device drivers for different hardware, such as the extended memory driver www.doorway.ru This is done in order for Windows 9x to use its bit driver for the CD-ROM drive, but if access to the CD-ROM drive is wanted before starting Windows 9x (e.g. if automatic start of Windows 9x is disabled, as earlier described), then MSCDEX HAS to be loaded from www.doorway.ru and therefore should be deleted from the www.doorway.ru file. Windows 9x's bit CD-ROM driver should be a little faster than a bit DOS driver, but some programs cannot run with the bit driver.
Loading and enabling a single CD-ROM device driver This example shows the relevant www.doorway.ru and www.doorway.ru commands for a computer with one CD-ROM drive. To configure your system to do this, you must make some adjustments to the parameters on your CD-ROM driver in the www.doorway.ru file and to the MSCDEX command. For CD-ROM in DOS you need a CD-ROM driver loaded in www.doorway.ru (GSCDROM, OAKCDROM or any other; www.doorway.ru is a popular one with good.
