INSTALLING SCO XENIX V.2.2 WITH ADAPTEC ACB-23XX
DISK CONTROLLERS
Adaptec ACB-23XX controllers are fully compatible with SCO Xenix V.2.2 and
newer. The following instructions describe the process for installing the Xenix
operating system on a disk subsystem using an Adaptec AT disk controller. The
following items are required to successfully perform this installation:
1) SCO XENIX V.2.2 or newer. Operating system software and
documentation
2) DOS 3.1 or newer, Operating system software and documentation
3) PC AT-compatible computer
4) Adaptec ACB-23XX disk controller
5) Hard disk drive (ESDI for use with ACB-232X, RLL for ACB-237X)
1.0 INSTALLING THE DISK SUBSYSTEM
First, the hard disk and controller must be installed in the AT and formatted for
use by the Adaptec controller. See Sections 2 (Hardware Installation) and 3
(Software Installation) of the Adaptec ACB-23XX User's Manual.
During the software installation process (Section 3 of the ACB-23XX User's
Manual), it is necessary to create a volume on the hard disk. At this point, a
single partition must be created that contains all of the available cylinders on the
drive. (Follow the instructions given for preparing a disk for use with DOS 3.3.)
When the hard disk has been successfully formatted with a single volume for the
entire disk, you are ready to proceed with the installation of the Xenix operating
system.
2.0 INSTALLING THE XENIX OPERATING SYSTEM
To install Xenix, follow the installation instructions given in the SCO XENIX
System V Operating System Run Time Environment (HW) reference manual.
The instructions are given in Chapter 2, "Installation Procedure"> During this
installation process, the dkinit program (invoked by hdinit) is used to set the
parameters for the hard disk. At his point, be sure to select option 1 (Display
current disk parameters) and verify that the values displayed for cylinders, heads
and sectors/track are correct If the parameters are not correct, please retry this
installation procedure. If correct, continue with the Xenix installation as directed.
If any problems are encountered during the Xenix installation, please see Section
2. 7 of the SCO Xenix, Run Time Environment (HW) reference for
troubleshooting information.
