I did a little web searching with your info. 1. I found a thumbnail description of the "mach speed MK8-939A" motherboard at http://www.machspeed.com/specs/viper/MK8-939A.html Unfortunately, this description doesn't identify the bios, but it's better than nothing. Off hand, I'd say this m/b will work ok with the latest EMC2 distribution based on Ubuntu 10.04 but you may need to explore the BIOS settings. 2. the "Applied Graphics Products Jeronimo J2/N" video card is probably an "Appian..." for which I found a thumbnail description at http://stason.org/TULARC/pc/graphics-cards/A-B/APPIAN-TECHNOLOGY-CGA-VGA-TARGA-XVGA-JERONIMO-J2-N-29.html According to this description, the board is based on a Cirrus Logic GD 5462 graphics chip. You should be able to confirm this by executing "lspci" at a command line prompt and looking for a line in the output that starts "nn:nn.n VGA compatible controller...." It's an old but still serviceable chip. [editorial note - before I could send this message I saw Gene Heskett's response. Maybe I should retract "serviceable".] You can look at /etc/X11/xorg.conf to see what driver is being loaded (in mine, for example, under section "Device" it says 'Driver "intel"'). I would expect the svga driver would work for you. If you look down the responses to the query in http://ubuntuforums.org/showthread.php?t=47368 you'll see some useful advice about using the command "dpkg-reconfigure xserver-xorg" to reconfigure the X server or alternatively forcing the kernel to load the cirrusfb driver at startup. Don't sweat the spelling of Schultz. Many years ago I was a military brat living in Germany. Now, I can't write S and H without putting a C in between them. The hard part was figuring out the reference to "Hogan's Heros." As Jon says, "I know nothing! NOTHING!!!!" Hope this helps.
