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.

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.
Standard VGA driver
If you are using a Matrox Impression VGA board in your PC and want to work with
the Windows standard VGA drivers supplied (e.g. for installation), you must set the
audio controller entry in the BIOS setup to Disabled. If you do not, errors may occur.
When the audio controller is set to Disabled, the Game Port is also disabled.
After the VGA driver of the Matrox Impression VGA board has been linked in, you
can set the base address of the audio controller.
A26361-D858-Z120-6-7619 7

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 setup menu 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
Exit - save and quit
The various menus are described below with all setting options. Since the
isetting 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)
– Display device (in the field marked Video Display)

Main Settings in BIOS Setup
Hard disk drives - Hard Disk 1 to Hard Disk 4
call the submenu to make corresponding settings of the IDE hard disk drive.
You should change the default settings only if you are connecting an
iadditional 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 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.

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.
!New values may only be defined for unused or newly partitioned hard disks.
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). Either an IDE drive has not been
installed, or the values have been set with Autotype Hard Disk.
1 to 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.

This field specifies the transfer mode for the IDE hard disk drive.
Standard One block is transferred for each interrupt (default entry).
2 Sectors, 4 Sectors, 6 Sectors, 8 Sectors, 16 Sectors,
The set number of blocks (sectors) is transferred for each interrupt.
LBA Translation - Addressing
This field enables and disables the LBA (Logical Block Addressing) mode. LBA
mode allows you to install and use hard disks with a capacity of more than 528
Mbytes. If a hard disk supports LBA mode, you can use the full capacity of the IDE
hard disk.
The default entry depends on the installed IDE hard disk drive. Change the default
entries only if you are installing another hard disk drive.
!You may only use IDE drives in the LBA mode selected when they were set
up. In other words, if you set up a hard disk with LBA mode Disabled, you
may only operate the hard disk with LBA mode Disabled.
Enabled If the hard disk supports LBA and it has a capacity of more than
528 Mbytes, the BIOS translates the hard disk parameters, allowing
the disk's full capacity to be used.
If the hard disk does not support LBA, its parameters are not
translated.
Disabled The BIOS uses the hard disk parameters and supports a maximum
capacity of 528 Mbytes.
PIO Mode - Transfer rate
The PIO (Programmed Input Output) Mode defines the transfer rate of the IDE hard
disk drive.
Standard 0,8 Mbyte/s to 2 Mbyte/s (default entry).
