Possible screen resolution Introduction
A26361-D912-Z120-3-7619 5
Possible screen resolution
The screen resolutions in the following table refer to the monitor controller on the
system board. You can set the screen resolution under Windows 95 using the
Refrate program.
If your PC was shipped with a graphics board, no monitor controller is installed on
the system board. The screen resolutions supported are then given in the
documentation accompanying the graphics board.
To set the screen resolution under MS-Windows click the start button, point to
Settings and then click Control Panel -Display properties (refer to MS-Windows
documentation).

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 „Add-on modules“-„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.

Important Notes Program with time loops
8A26361-D912-Z120-3-7619
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.
• 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.
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.

A26361-D912-Z120-3-7619 9
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 - power-management features
BIOSFaX - modem settings
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.
System settings - Main menu
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
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 „Add-on modules“-„Replacing the
lithium battery“).
Diskette A / Diskette B
These two fields are used to specify the type of floppy disk drive installed.
360K, 720K, 1.2M, 1.4M,2.8M
The entry depends on the floppy disk drive installed.
(Default entry Diskette A : 1.4M).
None A floppy disk drive is not installed.
(Default entry for Diskette B:).
