User Feedback :: several problems on persistency

sorry guys,
after 2 days wandering around the forum to find the answer, in the end i have to ask you for several questions:

I had frugal install DSL to my machine with following settings:
- hda1: CF 64 MB for DSL image
- hdb1: 15GB HD partition for config and data

1. How can I turn off the DHCP setting ?
I let it go and put in bootlocal.sh something like:
   sudo ifconfig eth0 xxxxxx netmask xxxxx
   sudo route add default gw xxxxx
but it can not manage to change my network card setting during boottime.
Any suggestion?

2. I had to install MyDSL application everytime i boot the machine. For now, I want only to install vncserver now for a start.  I couldn't find any configuration file that i can tweak to make it work. FYI, I have already use -restore option at boot.
Any suggestion?

Thank you for your help

thank you for the reponse guys,
unfortunately it doesn't work.

I have edited lilo.conf in /boot/ to add nodhcp as what ke4nt1 suggested but it still does not stop the dhcp.
So I come up with silly (but working) solution, I put:
    sudo killall pump
at bootlocal.sh before i put ifconfig....

concerning the myDSL, the VNCserver still doesnt installed automatically during boot time. Even I try to load with mydsl-load at bootlocal.sh and it still doesnt installed. I have to click it at desktop.
