The screen resolution depends on the connected monitor.
!You may set only those resolutions and refresh rates specified in the
"Technical data" section of the monitor description. Otherwise you may
damage your monitor. If you are in any doubt, contact your sales office or
customer service.
You can use the WDSETUP program (under MS-Windows) or the SET-VGA program
(under MS-DOS) to set the screen resolution. Detailed information is provided
under MS-Windows in the file VGA.WRI.

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 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 processor i486 DX2 or OverDrive
If you upgrade the system board by adding a processor mentioned above, please
note the following:
If you use the processor mentioned above, 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).

Primary CRT controller
You can set the primary CRT controller, by setting the jumper X180 to 6-15.
Color CRT controller = jumper X180 set to 6-15
Monochrome CRT controller = jumper X180 not inserted in 6-15
Default setting:
jumper X180 set to 6-15 = Color CRT controller
Processor
The jumper X180 8-17 always must be inserted. Depending on the processor type
inserted in socket D30, the jumpers X33 and X180 7-16 are inserted differently.
Socket D30 Jumper X33 Jumper X180 7-16
i486 SX, 25 MHz 1-2 ---
i486 SX, 33 MHz 1-2 inserted
i486 DX/i486 DX2/OverDrive,
25 MHz / 50 MHz 2-3 ---
i486 DX/i486 DX2/OverDrive,
33 MHz/66 MHz 2-3 inserted
--- = not inserted

Main memory
Two locations (X150 and X151) are available on the system board for connecting
memory modules. If you want to remove or insert memory modules you have to
remove the drive carrier (see "Technical Manual" for the PC).
!You may only use quick memory modules (Access time = 70 nsec or less)!
For the memory configuration we recommend the upgrade levels and slots
listed in the table .

Second level cache memory
The second level cache memory can be 0 Kbytes or 128 Kbytes in size. There are
5 sockets on the system board (D120, D130 to D133) for incorporating the SRAM
components.
You should set the following in the Setup menu in order to be able to use the
second level cache memory completely:
– Shadow BIOS ROM: SYSTEM AND VIDEO BIOS
– Cache: INTERN AND EXTERN
– Cache Shadow RAM: VIDEO BIOS ONLY
Upgrading
!Information on which SRAM components you can use is available from your
sales office or the customer service.
You may insert only a SRAM component 32Kbit*9, 15 ns into the socket
D120.
You may insert only a SRAM component 32Kbit*8, 20 ns into the sockets
D130 to D133.
Note the location of the SRAM chip when you plug in SRAM chip!
