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.
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.
A26361-D842-Z120-6-7619 5
Important Notes
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.
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 Pentium or OverDrive processor
Please note the following:
If you use one of the processors 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 one of our IT Service Shops.
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).

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 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.

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)
Fast PIO 1 2 Mbyte/s to 4 Mbyte/s.
Fast PIO 2 4 Mbyte/s to 5 Mbyte/s.

Cache - cache utilization
This field switches the cache on and off. The cache is a buffer to which parts of the
main memory and BIOS can be temporarily copied. The PC's performance is
higher when the cache is switched on.
You must disable the cache if:
– the access time is too short for older applications
– you are installing OS/2 Warp
Intern Only Only the internal cache is used.
Intern And Extern
Internal (first-level cache) and external cache (second-level cache)
are enabled. If there is no external Cache, only the internal cache is
used (Default entry).

PCI Interrupt Mapping INTx# - Assignment of the PCI interrupts
defines which PCI interrupt is switched to which ISA interrupt. For the change to
take effect, you must switch your PC off and then on again after the Setup BIOS
has terminated.
With multifunctional PCI boards, all PCI interrupts can be used. The controllers on
the system board do not need any PCI interrupts.
If you use a setting other than Auto, the Plug&Play functionality of the system BIOS
for PCI boards is deactivated.
The PCI interrupts INTA# and INTB# are assigned as follows:
PCI slot 1 = INTA#, PCI slot 2 = INTB#
Auto The PCI interrupts are assigned automatically in accordance with
the Plug&Play guidelines (default entry).
Disabled No PCI interrupt is used for the PCI board in the assigned PCI
slot.
IRQ03, IRQ04, IRQ05, IRQ06, IRQ07, IRQ09, IRQ10, IRQ11, IRQ12, IRQ14, IRQ15
The PCI interrupt is switched to the selected ISA interrupt. You may
not select an ISA interrupt that is used by a component on the
system board (e.g. controller) or an ISA board.
VGA Interrupt
assigns IRQ9 to the monitor controller on the built-in PCI module.
Enabled IRQ9 is assigned to the monitor controller on the built-in PCI
module. (Default entry)
Disabled IRQ9 can be used for other add-on modules.
To enable a change to take effect, exit the Setup menu, switch the device off and
then back on again.
PCI Parity Checking
specifies wether the PCI bus is to be parity-checked.
Enabled A parity check is performed on each access to the PCI data bus or
the PCI address bus. If a bit failure is detected an error message is
displayed. (Default entry)
