Could somebody please tell me how to stop dhcpcd from loading when the network is started and how to run dhclient instead so that my C3100 can get it's IP address from my local network?

ADDITION:

I have just realised that dhcpcd IS the dhcp client. Where do I find the config file?

On my server I have DHCP set up to give a fixed IP address to the Zaurus and it isn't doing so. I'd like to find out why.

FURTHER ADDITION:

Forget it! I made changes to the DHCP configuration file and forgot to restart the DHCP server.
All is now working as I would expect.
