Note that DirectCD for Windows 1.x and 2.x may not support the same set of
drives on all operating systems; for example, 2.0 only worked with drives
capable of using CD-RW media. If you're running WinNT, you need 2.x.
NOTE: There seems to be a great deal of misinformation about how to disable

One other note about DirectCD for Windows: in some situations you may have

usually found in c:\windows\system\iosubsys\.
Uninstalling DirectCD v3.01 or v3.01c may disable access to CD-ROM drives
under WinXP and Win2K. See section (4-49) for details.
