Is there a way to force 10.2 install to use external monitor?

[MadMax]

My internal monitor on my G3 Powerbook has had it. One of the ribbon cables is torn, so although I can barely see an image, it is not bright enough for me to read what's there and I don't have the installation sufficiently memorized to go through it "blindfolded". I have an external monitor but other than the initial startup apple logo, it switches back to the internal monitor. Is there anyway to change this behavior? If I could get the install to continue to use the external monitor, I would be golden.

run it with the lid closed, on boot it should not detect the builtin but detect the external only.

he has to have an external USB mouse and keyboard and the external monitor.
