Thanks Brian and Monmotha.... I hooked up my workstation to my linux box with a null-modem cable, but as Brian said, it still isn't a true console. The boot messages don't show up and the login prompt is the first thing to pop up. Brian, do you recommend any motherboards with a true console port? Thanks.
