The card runs fine under DOS, and when booting FreeBSD 2.1.5-R, but as the de0 driver loads, both the link light and the transmit/receive light on the SMC card go dead. The screen says: de0 rev 32 int a irq 11 on pci0:19 de0: DC21140 [10-100Mb/s] pass 2.0 Ethernet address 00:00:c0:5a:a8:e9 de0: enabling 100baseTX UTP port It's hard to judge by eye, but it seems like the card dies before the 3rd line of the output appears on screen. DOS also finds this card on IRQ 11. I poked around in the questions archives and discovered I needed to # ifconfig de0 -link2 to put the driver into 10Mb/sec mode, but that didn't help. The machine responds that it is "enabling 10baseT UTP port", but the state of the card (dead) doesn't change. A couple of times when issuing this command manually, I got the message: /kernel: de0: abnormal interrupt: 0xfc268504 [0x08100] This seemed to be triggered by issuing "ifconfig de0 -link2" more than once, but wasn't always repeatable. Does this suggest an IRQ problem? I tried adding the -link2 option to the de0 config during a re-install of FreeBSD but that didn't help. I also tried a modified kernel with minimal drivers enabled, but the result was the same. Other system components of note: ---------------------------------- Tyan-III Pentium 200 motherboard 256MB EDO RAM Adaptec 2940 SCSI CD-ROM (Sony?... runs fine on cd0) SCSI HDs (not installed yet) WD 1.2GB EIDE HD (with a small DOS slice and / inside the first 540MB) Any ideas for getting this fixed would be appreciated.
