Important Notes
!
Be sure to read this page carefully and note the information before you
open the PC.
Please note the information provided in the chapter "Safety" in the
Operating Manual of the PC.
Incorrect replacement of the lithium battery may lead to a risk of
explosion. It is therefore essential to observe the instructions in the
section "Replacing the lithium battery“.
The lithium battery must be replaced with an identical battery or a battery
type recommended by the manufacturer (CR2032).
Do not throw lithium batteries into the trashcan. Your vendor or dealer or
their authorized representatives will take used batteries back free of
charge so that they can be recycled or disposed of in the proper manner.
Connecting cable for peripherals must be adequately insulated to avoid
interference.
ADVARSEL
!
Lithiumbatteri - Eksplosionsfare ved fejlagtig håndtering. Udskiftning må
kun ske med batteri af samme fabrikat og type. Lever det brugte batteri
tilbage til leverandøren.
ADVARSEL
!
Eksplosjonsfare ved feilaktig skifte av batteri. Benytt samme batteritype
eller en tilsvarende type anbefalt av apparatfabrikanten. Brukte batterier
kasseres i henhold til fabrikantens instruksjoner.
VARNING
!
Eksplosionsfara vid felaktigt batteribyte. Använd samma batterityp eller
en ekvivalent typ som rekommenderas av apparattillverkarenfabrikanten.
Kassera använt batteri enligt fabrikantens instruktion.
VAROITUS
!
Paristo voi räjähtää, jos se on virheellisesti asennettu. Vaihda paristo
ainoastaan laitevalmistajan suosittelemaan tyyppiin. Hävitä käytetty
paristo valmistajan ohjeiden mukaisesti.
Modules with ESDs
Modules with electrostatic sensitive devices (ESD) may be identified by labels.

Important Notes Program with time loops
6A26361-D931-Z121-5-7619
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.
• Theequipmentandtoolsyouusemustbefreeofstaticcharges.
• 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.
CE certificate
This board complies with the requirements of the EEC directive
89/336/EEC with regard to "Electromagnetic compatibility".
Conformity was tested in the typical configuration of a Personal
Computer.
When installing the board, observe the specific installation notes in
the Operating Manual or Technical Manual for the appropriate
device.
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.

Settings in BIOS Setup
The BIOS Setup menu allows you to set your hardware configuration and system
functions. In addition, the BIOS Setup displays technical information on the PC's
configuration.
When it is supplied, the PC is set to factory default settings which you can alter in
the BIOS Setup menus. Any changes you make take effect as soon as you save the
settings and quit the BIOS Setup.
The Operating Manual describes how to call the BIOS Setup and change menu
entries.
You can select the following settings in the BIOS Setup:
Main - system functions
Advanced - advanced system configuration
Security - security features
Power - energy saving functions
Exit -saveandquit
i
The various menus are described below with all setting options. Since the
setting options depend on your PC's hardware configuration, some of
them may not be offered in the BIOS setup.
Main menu - System settings
In the Main menu you can set up the following:
• Time (in the field marked System Time)
• Date (in the field marked System Date)
• Floppy disk drive (in the field marked Diskette A or Diskette B)
• Hard disk drive (in the submenus of Hard Disk)
• System boot (in the submenus of Boot Options)
• Display device (in the field marked Video Display)

System Time / System Date
The System Time field and the System Date field show the time and date respectively
according to the PC. The time is shown in the format hh:mm:ss
(hours:minutes:seconds) and the date is shown in the format mm/dd/yyyy
(month/day/year).
!
If the settings in the System Time and System Date fields are frequently
wrong when you power up the computer, the lithium battery is dead.
Change the battery as described in "Replacing the lithium battery“.

These two fields are used to specify the type of floppy disk drive installed.

i
You should change the default settings only if you are connecting an
additional IDE drive to one of the two IDE connectors.
The maximum transfer rate of two IDE drives connected to the same
connector is determined by the slower of the two. Fast hard disks
should therefore be connected to the first IDE connector and identified
as Hard Disk 1 or Hard Disk 2; slower hard disks or other IDE drives
(e.g. CD ROM drives) should be connected to the second IDE
connector and identified as Hard Disk 3 or Hard Disk 4.
The following description of the setting options for Hard Disk 1 also applies to Hard
Disk 2,Hard Disk 3 and Hard Disk 4. The default settings depend on the installed
drive.

If you have installed a new unrecorded IDE hard disk drive, you should mark the
Autotype Hard Disk field and press Enter. This has the effect of setting the optimum
values for the IDE hard disk drive. You can change these values if you set the Type
field to User.
Type - Hard Disk Type
This field is used to specify the type of hard disk drive installed.
None You cannot change the hard disk parameters (Cylinders, Heads,
Sector/Track and Write Precomp). An IDE drive has not been
installed.
1to 39 The hard disk parameters (Cylinders, Heads, etc.) are preset.
Auto If the hard disk supports this mode, the setup menu reads the hard
disk parameters from the disk itself and sets them automatically.
You do not need to select the parameters yourself.
User You can enter the hard disk parameters (Cylinders, Heads etc.)
yourself.
If you have set the hard disk parameters with Autotype Hard Disk,
you can only reduce the values.
Examples of user-defined entries (IDE drives):
hard disk hard disk capacity
parameter 850 Mbyte 1Gbyte 1,6 Gbyte
Cylinders 1654 2097 3148
Heads 16 16 16
Sectors 63 63 63
Write Precomp None None None
CD If an ATAPI CD-ROM drive is mounted, this entry enables you to
boot from the CD-ROM drive.
Cylinders, Heads, Sectors/Track, Write Precomp - hard disk parameter
These hard disk parameters are set in accordance with the IDE hard disk drive. If
you want to change the hard disk parameters manually, set the Type field to User.
