Installation boot devices
One of the following boot devices is required
to install SCO OpenServer:
A CD-ROM drive that is configurable in your
system's BIOS as being a boot device, and that
does not use a proprietary boot format
A 3.5-inch floppy disk drive
An LS-120 drive
USB floppy drives and
USB LS-120 drives
cannot be used as boot devices
because the USB drivers are only available
from the installation image provided
on the SCO OpenServer System CD-ROM.
You can, however, use USB floppy and LS-120 drives
to load a Boot-Time Loadable Driver (BTLD)
during the installation process.
``Installing Boot-Time Loadable Drivers (BTLDs)''
for more information.

Configuring the CD-ROM drive as the boot drive
You can boot from the SCO OpenServer System CD-ROM
if your system BIOS supports CD-ROM as a boot option.
You cannot use this feature if
your system BIOS recognizes only a proprietary
bootable CD-ROM format.
To set your CD-ROM drive as the boot device:
Turn on your computer and
enter your system's BIOS configuration program.
Specify CD-ROM as the primary boot device (before C:
Save this change to the system BIOS and exit the configuration
Shut down your system.
Insert the SCO OpenServer System CD-ROM and remove any other media from
other boot devices on your system.
Proceed with the SCO OpenServer installation procedure, as described in
``The installation and upgrade procedure''.
Because not all SCO OpenServer installation utilities
are aware that the CD-ROM drive is emulating the
floppy drive, you might see an error message or prompt
that mistakenly refers to the floppy drive.
If you are using the bootable CD-ROM feature,
assume that messages you receive that refer to installation
media pertain to the CD-ROM drive.
Using EIDE CD-ROM drives
The ATAPI driver provides support for
Extended IDE (EIDE) CD-ROM drives by
representing the drive as a SCSI device to the operating system.
To present a consistent interface, the following restrictions apply:
A maximum of two IDE controllers can be present on any system.
No more than two IDE devices can be present on any one
If there are two devices on the controller, one must be configured as
a ``Master'' device and the other as a ``Slave'' device.
If only one IDE controller is present,
it must be configured as the ``Primary'' controller.
If there are two controllers, one must be configured as ``Primary'' and
the other as ``Secondary''.
The procedure for installing and configuring
EIDE- or IDE-interface hardware
(controllers, disk drives, ATAPI CD-ROM,
and ATAPI tape drives)
for your system is described in the
documentation provided by your hardware supplier.
Any information provided by your hardware supplier
might invalidate the information here.
Using USB CD-ROM drives
If you are using a USB CD-ROM drive
to install SCO OpenServer,
the SCO OpenServer installation prompts you to enter
the CD-ROM drive's USB device ID.
If the only USB storage device attached
to your system is the CD-ROM drive,
the drive's USB device ID is ``0''.
If, however, the system contains additional USB
storage devices (such as hard drives or Zip® or Jaz® drives),
the ID number for the CD-ROM drive
is dependent on the order in which the operating system
recognizes each of the detected USB storage devices.
In this case, you may need to cycle through the
USB device IDs
in the point-and-pick list until you
discover the ID currently assigned to the CD-ROM drive.
If your system contains a USB CD-ROM drive
that you would prefer to use for installing SCO OpenServer
but your system's BIOS only supports booting
from ATAPI devices,
you can use an ATAPI CD-ROM drive
as the boot device
and the USB CD-ROM drive
as the source for the installation itself.
To do this:
Insert the SCO OpenServer System CD-ROM
in the ATAPI CD-ROM drive
and boot the system to begin the installation.
When the installation prompts for information
about your CD-ROM drive,
move the SCO OpenServer System CD-ROM
to the USB drive
and then select the USB CD-ROM drive
as your installation device, as described in this section.
All USB devices that will be employed
during the SCO OpenServer installation
-- including CD-ROM drives, LS-120 drives,
or floppy drives from which you will install SCO OpenServer,
and storage devices, such as hard drives or Zip drives,
onto which you will install SCO OpenServer --
should be attached to the system before you turn
on the computer to begin the installation.
Additionally, once you begin installing SCO OpenServer,
it is recommended that you do not
attach or remove any USB devices (including hubs)
until the installation is complete.
