+.Sh DISTRIBUTION MEDIA
+The following files can be used to affect the operation of
+.Nm
+when used during initial system installation.
+.Bl -tag -width ".Cm packages/INDEX"
+.It Cm cdrom.inf
+A text file of properties, listed one per line, that describe the
+contents of the media in use.
+The syntax for each line is simply
+.Dq "property = value" .
+Currently, only the following properties are recognized.
+.Bl -tag -width ".Cm CD_MACHINE_ARCH"
+.It Cm CD_VERSION
+This property should be set to the FreeBSD version on the current
+media volume.
+For example,
+.Dq "CD_VERSION = 4.6" .
+.It Cm CD_MACHINE_ARCH
+This property should be set to the architecture of the contents on
+this volume.
+This property is normally only used with FreeBSD products that contain
+CDs for different architectures, to provide better error messages if
+users try to install Alpha packages on an i386 machine.
+For example,
+.Dq "CD_MACHINE_ARCH = alpha" .
+.It Cm VOLUME
+In a multi-volume collection (such as the FreeBSD 4-CD set), the
+.Pa ports/INDEX
+file on each disc should contain the full package index for the set.
+The last field of the INDEX file denotes which volume the package
+appears on, and the
+.Cm VOLUME
+property here defines the volume ID of the current disc.
+.El
+.It Cm packages/INDEX
+The package index file.
+Each package is listed on a seperate line with additional meta-data
+such as the required dependencies.
+This index is generated by 
+.Dq Li "make index" 
+from the
+.Xr ports 7
+collection.
+When multi-volume support is enabled, an additional field should be
+added to each line indicating which media volume contains the given
+package.
