hi all...

I am a new linux user )) I am using mandrake 9.1 my etherhet card is Surecom Ep320X. Linux is auto install this card but ican't use or change my network configuration. I am use webmin for change configuration details. When i change my ip adress to 10.0.0.120 webmin say me "SIOCFFLAGS:Resource Temporarily Unavaliable" and i don't know what doesn't mean this ???
How i repair this mistake and how i configure my network on mandrake 9.1 ??
So if i use mandrake controlcenter>Network & Internet menus write there card state down how i change "down" to "up"

So please for give me my very very bad english
