Hi All, (first of all my apologize if this mailing list is not the relevant place for my question) I use FC4 and installed a PCI Ethernet card based on chip RealTek 8139 and received the following info during probing: (...) 8139too Fast Ethernet driver 0.9.27 ACPI: PCI Interrupt Link [LNKG] enabled at IRQ 10 ACPI: PCI Interrupt 0000:01:0b.0[A] -> Link [LNKG] -> GSI 10 (level, low) -> IRQ 10 8139too: 0000:01:0b.0: unknown chip version, assuming RTL-8139 8139too: 0000:01:0b.0: TxConfig = 0xffffffff eth1: RealTek RTL8139 at 0xb800, ff:ff:ff:ff:ff:ff, IRQ 10 eth1: Identified 8139 chip type 'RTL-8139' (...) and when using ifconfig: eth1 Link encap:Ethernet HWaddr FF:FF:FF:FF:FF:FF inet6 addr: fe80::fdff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:4294960281 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Interrupt:10 Base address:0xb800 which seems correct ? but when starting pppoe: (...) 13 17:08:14 localhost adsl-connect: ADSL connection lost; attempting re-connection.

My questions: - what about an ethernet card without detected HWaddr ? - does it prevent to use it for pppoe or any Ethernet connections ? Thanks, Bruno
