Changing IP Numbers and DNS Lookup?? HELP?

[Paula J. Lindsay]

Hi everyone.
I am running fedora core 3.  My motherboard burned up over the holidays
and dell came out and install a new one yesterday. My resolution on my
display was mostly yellow so I tried several different sizes, the latest
was 1680x1240 or something like that.  Now when I reboot, I get the
message "cannot display this video mode" and it hangs. I tried fixing it
by booting from the cd and trying to find a way to fix it, but didn't
see an option, since it's the install disk, it just starts going through
the install, which isn't what I want to do.  I also boot and press F2
for setup, but there is no option to fix the display/resolution there
either.  Can anyone tell me how to get out of this mess? 
Many thanks in advance.
Paula
