possible to reduce DHCP boot timeout?

[Xenomorph]

i use my Laptop at home and school, and setting a static IP wouldnt work out too well when at school (lots of networks and hosts there).

i leave the laptop on DHCP, but during the many times i dont have a network cable plugged into it, it seems to take 5 times longer to boot.

i dont recall if the DHCP timeout is 30 seconds, 60 seconds, or whatever. i just know i'd like it to be just 5-10 seconds. if the system doesnt get a DHCP response by then, i just want it to get to the Desktop.

Disable your network card.

Enable it only when you need to use it.

Disable it afterwards.
