Hi, I recently got this DEC PC which has an 21142 ethernet chip onboard. Using -current's dc driver I get: Feb 17 19:37:39 p6 /kernel: Correcting Natoma config for non-SMP Feb 17 19:37:39 p6 /kernel: dc0: <Intel 21143 10/100BaseTX> port 0xec00-0xec7f m em 0xfdfffc00-0xfdfffc7f irq 11 at device 3.0 on pci0 Feb 17 19:37:39 p6 /kernel: dc0: Ethernet address: 00:00:f8:75:3c:6a Feb 17 19:37:39 p6 /kernel: miibus0: <MII bus> on dc0 Feb 17 19:37:39 p6 /kernel: dcphy0: <Intel 21143 NWAY media interface> on miibus 0 Feb 17 19:37:39 p6 /kernel: dcphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX- FDX, auto Using the de driver one gets: Feb 17 19:54:17 p6 /kernel: Correcting Natoma config for non-SMP Feb 17 19:54:17 p6 /kernel: de0: <Digital 21142 Fast Ethernet> port 0xec00-0xec7 f mem 0xfdfffc00-0xfdfffc7f irq 11 at device 3.0 on pci0 Feb 17 19:54:17 p6 /kernel: de0: DEC 21142 [10-100Mb/s] pass 1.1 Feb 17 19:54:17 p6 /kernel: de0: address 00:00:f8:75:3c:6a Feb 17 19:54:17 p6 /kernel: de0: driver is using old-style compatability shims The interesting thing is that the de driver works, the dc does not: Feb 17 19:38:48 p6 login: ROOT LOGIN (root) ON ttyv0 Feb 17 19:39:40 p6 /kernel: dc0: watchdog timeout Feb 17 19:40:02 p6 /kernel: dc0: watchdog timeout The machine has it's 21142 connected to a bulkhead panel with a UTP/10base2 connector. It cannot (unless the panel is swapped for a 100mbit one) do 100mbit UTP. What I wonder: why is the dc driver detecting a 21143 whereas the de sees a 21142 (which is the correct one BTW)? Are the chips not well enough distinguishable from the hardware perspective?
