I've got it!
I've disabled the APIC function from the BIOS and on startup I typed knoppix pci=biosirq.
Now my NIC is on IRQ 11 and it's working fine...

Until I can buy a new hard disk I'll use my network friends disk's
Linux Knoppix 3.3 latest is working perfectly now
Ur dooing a fine job with this Live-on-cd Linux!
