Important notes
!
Please note the information provided in the chapter "Safety" in the
Operating Manual of the PC.
The lithium battery on the board may only be replaced by specialist
technicians. There is a danger of explosion if this is not done properly.
The lithium battery must be replaced with an identical battery or a battery
type recommended by the manufacturer.
The lithium battery must be disposed of in accordance with local regulations
on the disposal of special refuse.
Be sure to read this page carefully and note the information before you
open the PC.
Modules with ESDs (electrostatic sensitive devices) 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.

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 80486
DX2
/50 MHz/66 MHz processor
If you upgrade the system board by adding an 80486
DX2
/50 MHz or
80486
DX2
/66 MHz upgrade processor, please note the following:
If you use the 80486
DX2
/50 MHz or 80486
DX2
/66 MHz processors, 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).
