Lasts magics were in the PCI/Pnp section. My bios shows this options: (Name = current Value : description) ( ** ** : option I think important for my problem)
__Clear NVRAM__ = No: Set this value to force the BIOS to clear the Non-Volatile Random Access Memory (NVRAM).The Optimal and Fail-Safe default setting is No. **__Plug & Play O/S__** = No : When set to No, BIOS configures all the device in the system. When set to Yes and if you install a Plug and Play operating system, the operating system configures the Plug and Play device not required for boot. __PCI Latency Timer__ = 64 : Value in units of PCI clocks for PCI device latency timer register. __Allocate IRQ to PCI VGA__ = Yes: When set to Yes will assigns IRQ to PCI VGA card if card requests IRQ. When set to No will not assign IRQ to PCI VGA card even if card requests an IRQ. __Palette Snooping__ = Disabled : This item is designed to solve problems caused by some non-standard VGA card. __PCI IDE BusMaster__ = Enabled: When set to enabled BIOS uses PCI busmastering for reading/writing to IDE drives. __OffBoard PCI/ISA IDE Card__ = Auto : Some PCI IDE cards may require this to be set to the PCI slot number that is holding the card. When set to Auto will works for most PCI IDE cards. **__IRQ3 / 4 / 5 / 7 / 9 / 10 /11__** = Available (for each of them, second option is : Reserved) : This item allows you respectively assign an interruptive type for IRQ-3, 4, 5, 7, 9, 10,11. **__DMA Channel0 / 1 / 3 / 5 / 6 / 7__** Available (for each of then, second option is : Reserved): When set to Available will specified DMA is available to be used by PCI/PnP devices. When set to Reserved will specified DMA will Reserved for use by legacy ISA devices. **__Reserved Memory Size__** : This item allows you to reserved size of memory block for legacy ISA device. I tried to reserve IRQ5 and 7 and/or DMA channel (5 and 7 or all). It doesn't seem to change anything. I don't know what to tune. Is it possible that my HW is not powered ? Or would this has prevent "normal" interface configuration 2010/11/14 Wolfgang Grandegger <[email protected]> > On 11/14/2010 08:36 PM, Willy Lambert wrote: > >> > >> r...@alpha:/opt/ard# cat /proc/interrupts > >> CPU0 CPU1 > >> 0: 153590 153124 IO-APIC-edge timer > >> 1: 0 2 IO-APIC-edge i8042 > >> 5: 0 0 IO-APIC-edge can0 > >> 7: 0 0 IO-APIC-edge can1 > > I assume that you already send some messages.
