I just got an Optiplex 740 here at work and am trying to get Linux installed on it. Fedora core 6 is my flavor, and am having all kinds of troubles of course. acpi=off is necessary, and the mouse freezes constantly. I see there's a new bios for this system posted 3.28/2007. I am hoping this is the fix we are both looking for. But I am trying to find out a good way to update the BIOS on this stupid box. No floppy drive and of course if you aren't running windows, Dell wants you to boot into a DOS environment and run the exe from there. Can't we get something a little more friendly when you don't have an OS on the system, or you are using a real OS?
