Hi,

i make some more tests with 
1) an old APCI1500/PCI card no linux driver support -> so i don't need to 
unload the module.
2) my second network-card Realtek 10/100 MBit.

Both don't work at all. Only my first gigabit-onboard-network-card starts.

Here the output from userspace/dmesg:


1) // Applied Micro Circuits Corp. APCI1500 Signal processing controller

Sould i update the BIOS if possible/available?

Could it be a problem with the already assigned patches? (See the first E-Mail 
:The VTD [PATCH1/2] seems already be applied. )
