Mounting the CD-ROM:

The disk is in ISO9660 format, the universal format for CD-ROM data.  On
a PC with MSCDEX.EXE installed, the disk will mount automatically when
it is inserted.  If the CD-ROM drive is drive d:  you can do a directory
or copy files from the CD without additional software.

Unix workstations default to a propietary CD-ROM filesystem, but allow a
standard ISO-9660 disk to be read it an appropriate mount command is
issued *by the superuser*.  Here are a few mount commands copied from
the excellent book `Unix Power Tools':

SunOS           #/etc/mount -r -t hsfs /dev/sr0 /cdrom
IBM AIX         #/etc/mount -r -v cdrfs /dev/cd0 /cdrom
HP-UX           #/etc/mount -r -s cdfs /dev/dsk/c201d2s0 /cdrom
DEC Ultrix      #/etc/mount -t cdfs -o noversion /dev/rz3c /cdrom
SCO             #/etc/mount -r -fHS,lower,intr,soft,novers /dev/cd0 /cdrom
SGI IRIX        #/etc/mount -o ro -t iso9660 /dev/scsi/sc0d510 /cdrom
Linux (SCSI)    #/etc/mount /dev/cdrom
The man mount command on your system will show you the correct format
for your system.
