Hi Mathias, yes it's a nice gigabit mobo with pci-e and gigabit integrated network. I choose that mobo because has 4 pci that we need for our sensor cards, netword cards, and capture cards. I prefer to use the pci intel card because they works with rtnet and the election of the hardware is very important with linux/xenomai/rtnet. I don't want to use the gigabit network card for rtnet because it's connected to a gigalan. This box will work as controller. > This means an invest in hardware but this should help you here...

I thought, that APIC is > required for multi CPU systems?!? yes it's a dual core amd64: processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 67 model name : AMD Athlon(tm) 64 X2 Dual Core Processor 5400+ stepping : 3 cpu MHz : 2812.844 cache size : 512 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt rdtscp lm 3dnowext 3dnow pni cx16 lahf_lm cmp_legacy svm extapic cr8_legacy bogomips : 5629.23 TLB size : 1024 4K pages clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management: ts fid vid ttp tm stc this messages repeated for: processor : 1 vendor_id : AuthenticAMD cpu family : 15 ..... the boot parameters that I have in the grub are: kernel /boot/vmlinuz-2.6.22-xenomai-2.4-rc5 root=/dev/sda2 ro noapic because are the _only_ one that I can use to boot, if not the sata controller doesn't works. And as you can see it's no required for dual core systems. Now, to me the main question is why I choose some assignment of irqs in the bios and the rtnet driver doesn't use it and chose another one....
