Notes
If you are trying to play an
audio CD with Windows CD
Player and you insert a second
audio CD in another CD-ROM
drive, the first audio CD stops
playing, Windows CD Player
restarts, and then Windows CD
Player plays the second audio CD
that you inserted into your CD-
ROM drive. This behavior occurs
only if both CD-ROM drives are
using a Windows protected-
mode driver and you have the
Auto Insert Notification feature
enabled.
CD-ROMs that contain an
Autorun.inf file are played
automatically when you insert
them in your CD-ROM drive. The
Cdvsd.vxd driver polls
repeatedly to detect the
presence of a CD-ROM. When a
CD-ROM is detected, Windows is
notified that a new volume is
available and the drive is
checked for an Autorun.inf file.
If found, programs that are
listed on the open= line in the
[AUTORUN] section are run.
If the volume is determined to
be an audio CD, Windows
performs the default action, if
any, that is associated with that
file type. "Play" is the default
action for the audio CD file type.
Windows does not play CD-ROMs
automatically if you are using
only real-mode CD-ROM drivers.
Protected-mode drivers are
required to play CD-ROMs
automatically when you insert
them in your CD-ROM drive.
