How to thank mad biker for THE solution to my question?

I wanted to know how to disable the LAN option/function on my HP computer. BIOS boot priority doesn't list this on my machine. The new combo-card I'd fitted was suspect, but by following Mad bikers direction - to look under device security - (not the obvious place I must say) I found a Networking option enabled (not LAN) which when disabled solved my boot-up sequence time delay problem - thank you Mad biker and thanks to all who responded to my cry for help. Very very sorry for the excessive delay - I have yet to discover how to target the person to thank directly via this Yahoo Answers site.
