OK, ieee1394 is firewire. Do you have any firewire devices plugged in? If so, unplug them and try the installation again. If not, read on.
I stuck in my MDK 10 installer cd and what should happen next is the switch to graphics mode (ie, XFree should come up).
This could mean that your video card isn't detected properly. Or it could be that the system is hung after loading the firewire drivers, or trying to load some other driver. I can't tell you which at this stage, I'll need more info.
Try going to ALT-F7. What do you see?
Next look at ALT-F2. That should be a shell prompt (From the ALT-F7 screen you may need CTRL-ALT-F2 to get to ALT-F2). From the ALT-F2 screen, try typing 'dmesg' and press Enter. What do you see?
What kind of video card do you own? Is it listed on the mandrake 10 hardware compatibility list?
