>Description:

Installing using 1.3-release boot floppy on a P5-100 with a NetGear
FA310TX (21140-AE based) ethernet connected to 100bTX. When I gave
sysinst the info about the network (not knowing what string to enter
for "media", I left it as "default"), it paused for a very long time,
then said that it had failed to initialize the network. When I looked
at ifconfig, it gave something like this:

de0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,OACTIVE,SIMPLEX,MULTICAST> mtu 1500
        media: autoselect (100baseTX) status: active
        inet 137.175.81.252 netmask 0xffffff00 broadcast 137.175.81.255

and sure enough, ping didn't work. So I ifconfiged the card by hand:

  # ifconfig de0 137.175.81.252 netmask 0xffffff00

and ping worked just fine. Looking at the ifconfig again, I saw:

de0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        media: autoselect (100baseTX) status: active
        inet 137.175.81.252 netmask 0xffffff00 broadcast 137.175.81.255

The only difference is that OACTIVE is off.
