No Display in LFT Monitor

Help! I have installed the GXT250P adapter card and its corresponding
fileset.

However when I try to install my new AOC Monitor to the graphics
adapter card the system was not able to continue it just displays a _
on the monitor. I have already configured my console to work as a LFT.
Another thing is that my monitor, keyboard and mouse will only work
during the SMS utility but will not display the prompt during bootup.

Is there something that I forgot to install or to configure? Thanks!
