You'll have to set ewa_mode in SRM, I think, to use 100/half or autosense. Otherwise the transceiver on the NIC and/or the hub keep flipping back and forth, and things just suck. > de0: port 0x1ffef00-0x1ffef7f mem 0x7efff00-0x7efff7f irq 8 at device 2.0 on pci0 > de0: interrupting at IRQ 0x0 intA (vec 0xb80) > de0: DEC DE500-XA 21140 [10-100Mb/s] pass 1.1 > de0: address 00:00:f8:00:3c:ec > de0: enabling Full Duplex 100baseTX port I think some DE500s have problems going at 100/full even on a proper 100Mbit switch.. the one in my PWS500au (miata) crawls as 50-100kB/sec when everything is forced to 100/full. Much happier at 100/half, so I set the ewa_mode and the switch port speeds to match. I think this is fixed in later revisions of the DE500. Anyone working with Sun machines and the hme card know all about the evils of marginal speed/duplex settings.. so simple, yet such a perennial pain... #!/jameel/akari sleep 4800; make clean && make breakfast To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
