Before installing

Installing and configuring hardware devices

Installing and configuring hardware consists of physically installing hardware controllers, running hardware setup programs, and configuring software controllers to support the new devices.

After the hardware is physically installed and configured, you are ready to install SCO OpenServer. Software controllers for most hardware devices are configured automatically by the installation.

If your system experiences installation difficulties because of hardware problems, such as conflicting IRQs or drivers recognizing hardware incorrectly, you can manually configure drivers by running the Device Configuration Utility (DCU) from within the SCO OpenServer installation. See ``Installing and configuring hardware'' for more information.

Hard disk detection

By default, SCO OpenServer is installed on the primary hard disk found for the primary Host Bus Adapter (HBA). Note that the installation also gives you the option of selecting a different hard disk for installation, if desired.

NOTE: SCO OpenServer cannot install on a device that is not detected. Be sure to review the device information presented on the installation screens, so that you do not inadvertently install SCO OpenServer on a secondary disk because the primary disk is not found. If a secondary disk is not present and the primary disk is not detected, the installation warns that it cannot proceed.

The rules for determining which hard disk is the primary drive are:

Disks attached to IDE interfaces always take precedence over disks attached to SCSI HBAs.
Ordinarily, IDE interfaces are designated primary and secondary by their physical setup (jumpers, for example).
IDE disks are usually designated as master and slave by jumper settings on the disk drive.
SCO OpenServer will install on the first IDE disk that is discovered. IDE disks are detected in the following order: primary master, primary slave, secondary master, and finally secondary slave.
NOTE: SCO OpenServer does not support devices in a slave-only configuration. If there is only one device on a given IDE interface, it must be configured as master.
When multiple SCSI HBAs are present, by default, the HBA with the lowest BIOS address is primary.
With SCSI disks, the disk with the lowest target ID is used as the primary disk. This is typically ID 0, but it can be otherwise. Most SCSI BIOSs allow the selection of the bootable target ID.
To install SCO OpenServer on a disk other than the one with the lowest numerical target ID or on a disk attached to a SCSI HBA other than the one with the lowest BIOS address, you must override the default disk selection.
NOTE: If you choose to install SCO OpenServer on a disk other than the default disk selected by the installation, you must ensure that your system BIOS is configured to actually boot from the desired disk. There is no way for SCO OpenServer to adjust your BIOS to boot from the disk of your choosing.
It is recommended that you detach all external USB hard disks before starting an SCO OpenServer installation. This precaution will prevent any possibility of accidentally installing SCO OpenServer on the USB hard disk.

You must be familiar with your system's physical configuration before you begin the installation. When the hardware diagnostics are run as the system first powers up, check the console messages for recognition of your devices. If you do not see what you expect, check the system BIOS setting to make sure there are no conflicts. Check power and bus cables to make sure they are well attached.

Once the SCO OpenServer HBA autodetection is complete during the installation process, you can use <Alt><SysReq>h to switch from the installation screen to the system console (VT0) to see diagnostic messages for devices that successfully load. HBA and disk information may be present on the screen. Use <Alt><SysReq><F1> to switch back to the virtual terminal running the installation.

When configuring disk setup, verify the disk sizes being reported on the screen as well as the device names being presented. Device names contain the information about the controller and target ID for the disk to which it refers.

Supported Host Bus Adapters (HBA)

SCO OpenServer Release 6 supports the following Host Bus Adapter (HBA) drivers.

NOTE: A subset of these drivers, as represented in this table, are included in the CD boot image and thus available for automatic detection when the installation begins.

If your system requires one of the other supported HBAs, you will need to extract it from the SCO OpenServer installation CD or from a separate disk containing the necessary updated or third-party driver(s). You can extract HBAs from any of these sources as part of the installation process.

Installation boot devices

One of the following installation media devices is required:

a bootable CD-ROM drive
a supported network adapter, and a preconfigured network installation server, for network installation. See ``Installing SCO OpenServer products over the network'' for information on performing an installation over the network.

Note the following about SCO OpenServer bootable CD-ROM support:

SCO OpenServer Release 6 bootable CD-ROM support uses the ``El Torito'' extension of the ISO 9660 standard, in no-emulation boot mode.
The system must allow you to specify CD-ROM as a boot device in the system BIOS, and must not use a proprietary CD-ROM boot scheme.
Set the boot sequence of your system BIOS to start with the CD-ROM drive.
For SCSI CD-ROM drives, set the SCSI controller so that BIOS support for bootable CD-ROM is enabled. Also ensure that the start-up or boot device sequence set in the BIOS includes the CD-ROM device before the network device.
The SCO OpenServer Release 6 installation automatically detects the CD-ROM drive to use. If your system contains multiple CD-ROM drives, make sure that the installation CD-ROM drive contains the SCO OpenServer Release 6 CD and that all other CD-ROM drives are empty. Otherwise, you run the risk that the wrong drive will be detected for installation.
