When I connect a video card in my sunfire V240, nothing appears on the screen. At first I thought that the card does not functioned. But by testing on a xserve, I realized that there was something that was displayed on the screen. So I think it just might be an option in the alom! ... I do not know. What do you think?
Please check your video card manual which Solaris, driver(s) and/or patches are required and how to configure the X11 server to redirect the display to this output. You can too check if you can redirect the console output to this card if you want it.
apparently, there should already have a system installed on the sun to install the driver for the card. So first install the system via the serial interface in the first place? There is no faster? the card is a "xvr600"
