DOS - Invalid Drive message

For some reason I am getting an invalid drive message for my CDROM drive in DOS. In windows 98, it works fine. How can I fix this? I need to install a new OS from CD.

In DOS you need load CDROM driver (in C:\CONFIG.SYS file) and to assign CDROM letter to drive (in C:\AUTOEXEC.BAT file).
For more info read here:
Note, CDROM drivers are provided by manufacturer of CDROM drive. It may be a real pain to find apropriate DOS driver (*.SYS).

If you need to install a new OS from CD, it's better to boot from that CD (it's probably bootable, just change boot sequence in your PC SETUP screen), not to install it from DOS.

To be specific, I changed the boot sequence. That was exactly what I was looking for. Thanks again, I nearly went insane.
Thank you. be carefull to not daamage your existing Win98 installation, when installing new OS.
