 Previously I've added hints to /boot/loader.conf and booted GENERIC with 
 ACPI disabled. Moving hints to /boot/device.hints does not help!
 That's why I've asked if the syntax:
 hw.pci13.0.INTA.irq="16"
 hw.pci15.0.INTA.irq="17"
 hw.pci5.0.INTA.irq="19"
 is correct?
 
 I am still getting "No I/O APIC 0 to route interrupt to" as shown in
 http://www.lecad.uni-lj.si/~leon/other/x7sb4/img_1650.jpg
 
 I've also tried to boot OpenSUSE 10.3 that has kernel 2.6.21.5-31 and it 
 boots with or without ACPI.
 http://www.lecad.uni-lj.si/~leon/other/x7sb4/img_1651.jpg shows dmesg and 
 /proc/interrupts with acpi=off
 http://www.lecad.uni-lj.si/~leon/other/x7sb4/img_1652.jpg is the same with 
 enabled ACPI (default)
 
 Linux appears to work well with this board. Even handles reboot well while 
 FreeBSD 7.0 after upgrade does not as I staded before and shown in photo

 Kind regards!
