When installing a SCSI CD-ROM drive,
you must use a SCSI host adapter supported by
SCO OpenServer systems. You should also check with your hardware
supplier that the drive will work with the host adapter.
NOTE:
ATAPI-2-compliant drives connected to an EIDE
controller are also supported using the same driver
used for SCSI devices. At boot time, IDE
controllers and CD-ROM drives are listed as in
this example:
You can mount an ISO 9660, High Sierra, or Rock
Ridge format CD-ROM as a read-only filesystem.
This allows access to files which are described by the
primary volume descriptor on the CD-ROM. Access
to files described by secondary volume descriptors is not
supported.
A maximum of 255 SCSI CD-ROM
drives per system are supported;
seven per SCSI 1 bus, or fifteen on a 16-bit-wide
SCSI 2 bus. The device files used for access to the
CD-ROM drive are documented on the
cdrom(HW)
manual page.
CD-ROM filesystems containing extended attribute
records are supported. You can access record format
information and the file access permissions in an extended
attribute record using options to
mount(ADM).
For EIDE/ATAPI drives, you will need to specify
whether it is attached to a primary or secondary controller and
whether it is configured as master or slave.
For SCSI drives,
you will need to specify the SCSI host adapter type,
the host adapter number, target ID, and
logical unit number (LUN) as described in
``SCSI addresses''.
If this is the first SCSI peripheral that you are
adding to the SCSI bus controlled by a host
adapter, you may need to supply additional hardware
information about the adapter as described in
``Adding a SCSI peripheral device''.
To add a CD-ROM drive:
Log in as root and put the system into maintenance mode.
Select CD-ROM from the devices
listed by the Hardware/Kernel Manager, or
enter the command mkdev cdrom.
Select to install the appropriate CD-ROM type from the main menu.
If the CD-ROM driver is not already configured
into the kernel, choose to configure it for use.
For EIDE/ATAPI drives, enter the controller
number and identify the drive as master or slave.
For SCSI drives,
enter the type and number of the host adapter. If the
adapter driver is not already configured into the kernel,
enter the requested hardware configuration information.
Confirm the values displayed. When prompted,
enter the details of the SCSI address of the
drive and confirm the information.
Do not enable support for the CD-ROM/tape
installation device driver. (You would only require this
driver to read an install CD-ROM supplied with an
earlier version of the operating system.)
If this is the first CD-ROM drive on your system,
specify that you want to add support for the High Sierra
filesystem. DOS CD-ROMs generally use the High
Sierra format, so you will also be able to access data from
these with this setting.
Relink the kernel, then reboot the system. You can defer
relinking if you have other devices to configure.
NOTE:
To bring the CD-ROM drive online, you must insert
a disk. If you attempt to bring up the drive without
inserting a disk, the message cannot open is
displayed.
