Hi, I'm looking to set up a multi-head (ideally >= 3) system using an UltraSPARC board with PCI slots. As I see it the problems / solutions are:
*. On PCs multiple graphics cards tend to clash address ranges - I am under the impression this doesn't occur with Sun kit. *. Most PC graphics cards require some BIOS code to be run. This should be able to be circumvented by: 1. Using cards with OpenBoot PROMs (IE official Sun graphics cards). 2. Using cards which can be set to not require any from the BIOS (IE Matrox Millenium) 3. Using the BIOS emulation in the latest versions of XFree *. Linux/SPARC XFree86 only has drivers for a handful of graphics cards (i/c some PC ones if I understand correctly). The solution is to use framebuffer support in the kernel and the unaccelerated fbdev driver in XFree86 Considering all of this what I'm considering is fitting the Box with one Sun PCI graphics card (so it has something to boot on) and adding several Matrox Millenium cards (jumpered so they don't require BIOS initialisation). If this works I might look at replacing the Matrox cards with something more modern, if I can find cards that don't need BIOS initialisation and have either a frame buffer or a Linux/SPARC XFree86 driver (in stable I think this is ATI Rage, Rage 128, Radeon and Glint). Has anyone tried this? Is it possible? Is there (some|any)thing I haven't thought of? Can anyone suggest newer PC graphics cards that fit the above requirement? Would I be better off looking at DRI? Sweet Dreams, - Martin PS if anyone could enlighten me as to the use of the atimisc driver (which doesn't seem to be documented on the XFree86 site) I'd love to know. -- Martin [EMAIL PROTECTED] "Seasons change, things come to pass"
