1.5 Safety instructions for the described product
DANGER
Fatal injury hazard through ineffective Emergency-OFF devices!
Emergency-OFF safety devices must remain effective and access-
ible during all operating modes of the system. The release of func-
tional locks imposed by Emergency-OFF devices must never be al-
lowed to cause an uncontrolled system restart! Before restoring
power to the system, test the Emergency-OFF sequence!
DANGER
Retrofits or modifications may interfere with the safety of the prod-
ucts described hereunder!
The consequences may be severe personal injury or damage to
equipment or the environment. Therefore, any system retrofitting or
modification utilizing equipment components from other manufac-
turers will require express approval by Bosch.
DANGEROUS ELECTRICAL VOLTAGE
Unless described otherwise, maintenance procedures must always
be carried out only while the system is isolated from the power sup-
ply. During this process, the system must be blocked to prevent an
unauthorized or inadvertent restart.
If measuring or testing procedures must be carried out on the active
system, these must be carried out by trained electricians.
CAUTION
Only Bosch-approved spare parts may be used!
CAUTION
Danger to the module!
All ESD protection measures must be observed when using the
module! Prevent electrostatic discharges!

Safety Instructions 1–7
1070 073 825-103 (02.04) GB
Observe the following protective measures for electrostatically endangered
modules (EEM)!
DThe Employees responsible for storage, transport and handling must be
trained in ESD protection.
DEEMs must be stored and transported in the protective packaging speci-
fied.
DOut of principle, EEMs may be handled only at special ESD work stations
equipped for this particular purpose.
DEmployees, work surfaces and all devices and tools that could come into
contact with EEMs must be on the same potential (e.g. earthed).
DAn approved earthing wrist strap must be worn. It must be connected to
the work surface via a cable with integrated 1 MWresistor.
DEEMs may under no circumstances come into contact with objects sus-
ceptible to accumulating an electrostatic charge. Most items made of
plastic belong to this category.
DWhen installing EEMs in or removing them from an electronic device, the
power supply of the device must be switched OFF.

2.4.1 BIOS Setup
PCI slot x In the BIOS submenu called “The Advanced Menu / PCI Configuration sub
menu”you can assign the interrupt request (IRQ) address to a specific PCI
slot. At the same time, the number of the IRQ address also defines the prio-
rity. If only PnP cards are used, then the BIOS setup ”AUTO”must be main-
tained.
BIOS selection:PCI IRQ line 1, PCI IRQ line 2, PCI IRQ line 3, PCI IRQ line 4
Option: Disabled, Auto, IRQ: 3, 4, 5, 7, 9, 10, 11, 12, 14, 15,
Default:AUTO
ISA slot (IRQ)
In the BIOS submenu ”The Advanced Menu / PCI Configuration sub menu /
PCI/PNP ISA IRQ Resource Exclusion / IRQx”, the IRQ Address for Legacy
ISA cards (ISA cards without plug-and-play capability) can be assignedper-
manently.
BIOS selection: IRQ:3, 4, 5, 7, 9, 10, 11, 15
Option: Available, Reserved
Default:Available
ISA slot (UMB) In the BIOS menu “The Advanced Menu / PCI Configuration sub menu /PCI/
PNP ISA UMB Region Exclusion”you can reserve a specific upper memory
block for Legacy ISA cards (without ”plug–and–play”capability) .
BIOS selection: C800 - CBFF, CC00 - CFFF, D000 - D3FF, D400 - D7FF,
D800 - DBFF, DC00 - DFFF
Option: Available, Reserved
Default: Available
CAUTION
Address conflicts (IRQ, memory access, I/O address) may cause
destruction of motherboard or ISA cards!
Please follow the instructions provided by the card manufacturer. If
necessary you must make new configuration settings in the BIOS
and in the operating system (e.g. Windows NT control panel).
