This short document will guide you through the steps needed to configure a virtual CD-ROM drive on your DOS computer. This will let you run games that normally require a CD-ROM, even on computers that do not have a physical CD-ROM drive installed.
As a result, your games will run much faster, and you will not need to change CD's and cause undue wear on them. There is one drawback though. If the game relies on CD-Audio, you will not be able to hear the background music. If you know of a way or a workaround to enable CD-Audio, I'd like to know! :) Thanks.
In this example we copy the files from D: (physical, REAL CD-ROM) to C: inside the directory CC-GDI.
C: CD\ MD C:\CC-GDI XCOPY D:\ C:\CC-GDI /S /H
C:\CC-GDI, and we want the virtual CD to be drive E: so use:
SUBST E: C:\CC-GDI
BCD E: /n:1 /l:"GDI"
SUBST E: C:\CD1 SUBST F: C:\CD2 BCD E: /n:2 /l1:"CD1" /l2:"CD2"
