Setting The Bios - Siemens SIMATIC IPC547E Operating Instructions Manual

Exclusive PCI hardware interrupt
Applications demanding a high-performance interrupt require a high-speed hardware
interrupt reaction. The PCI hardware interrupt should be used only by one resource in order
to ensure high-speed reaction of the hardware.
Setting up an exclusive interrupt on the device (APIC mode only)
An exclusive interrupt can only be used for PCI slot 4 and PCI slot 5. Further exclusive
interrupts for use at the slots are not available.
Assigning exclusive interrupts in BIOS Setup (PIC mode only)
The interrupts are automatically assigned to the slots at system startup due to the default
settings in system BIOS. Several slots may share the same interrupt, depending on the
system configuration. This functionality is known as interrupt sharing.
Exclusive interrupts are not available in PIC mode. Disable specific system resources in
order to obtain exclusive interrupts. BIOS assigns the PIC interrupts at random during restart
of the system.

Note
After a BIOS update, you need to execute the "Restore Defaults" command. Executing the
"Restore Defaults" command restores all BIOS settings to their original state.
