Important notes
!Please note the information provided in the chapter "Safety" in the
Operating Manual of the PC.
The real-time clock chip on the system board includes a lithium battery
which may be replaced only by authorized personnel. Incorrect handling
may lead to a risk of explosion.
The chip may be replaced only with an identical chip or with a type
recommended by the manufacturer.
The chip must be disposed of in accordance with local regulations
concerning special waste.
Be sure to read this page carefully and note the information before you
open the PC.
Modules with electrostatic sensitive devices (ESD) may be identified by labels.
When you handle modules fitted with ESDs, you must observe the following points
under all circumstances:
– When you handle modules fitted with ESDs, you must always discharge yourself
(e.g. by touching a grounded object) before working.
– The equipment and tools you use must be free of static charges.
– Pull out the power plug before inserting or pulling out modules containing ESDs.
– Always hold modules with ESDs by their edges.
– Never touch pins or conductors on modules fitted with ESDs.

Important notes
Notes on software
Program with time loops
Problems can occur with programs in which time loops have been implemented
through software loops. This applies in particular to older programs which were
written for 8 MHz processors.
SCO-UNIX on devices with Pentium processor
If you use the Pentium processor, the Adaptec-SCSI controller cannot be
addressed under SCO-UNIX 3.2.4 and ODT 2.0.
To solve this problem, you can order from SCO a set of SLS (Support Level
Supplement) floppies (consisting of 3 floppy disks) under the number uod361,
free of charge, or contact SNI's spare parts service.
The problem no longer exists in the new releases of SCO-UNIX 3.2.4.2 and
ODT 2.1.
There will be no support for older versions (SCO-UNIX versions lower than 3.2.4
and ODT versions lower than 2.0).

Settings and add-on modules
You can make settings in the setup menu or using the jumpers on the system

Settings in the setup menu
The setup menu displays settings and technical information on the PC
configuration. The Operating Manual describes how to invoke the setup menu and
change menu entries. Pressing the function key F1 provides help information on
each entry field.
