How to use IMS Twin Turbo 128M

[Chris Plummer]

I have IMS Twin Turbo 128M cards in both an 8500 (running YLD 2.2) and
an 8600 (running YLD 2.3). I'd like to hook up monitor to the IMS cards
rather than the built-in video, the main reason being because I don't
want to buy the stupid mac->vga adapter. I think they are also faster
than the built-in video, but I'm not sure of this.

What do I need to do to get YLD to use the IMS card as the main video
both at the boot time (and at the text login screen), and when I launch
KDE with startx?

Thanks,

Chris Plummer
