1. How many time it take ? I have a P4 1.6 GHz.
Can't say exactly but expect it to take a couple of hours.

2. Can I work while it compile/install? ie. I can stay on my KDE and don't need to restart computer to text mode only.
You can keep using you KDE but some things may stop working when things start to get installed. If you have all applications you need open you may not notice it. But if you are lauching and killing applications or running commands then you may notice some problems. At least that is my experience.

3. Is it installing all at the end or all packages one by one just after theire compilation?
I'm not sure but I think that it compiles and installs one by one: kdebase, kdenetwork, kdepim, etc

4. And what happens if it doesn't work at middle of the install and then abord the process? Corrupted KDE?
Well, I think thats why Konstructs installs KDE in the home dir by default. To avoid such things. But since you want't to override the old KDE then I recommend reading the docs before starting. Check that you have everything that is needed. If it fails anyway...well, fix the problem and restart the process :-) I don't think that you will ever need to be at the command line. If I'm not mistaken the first thing that is installed is kdebase. That is the base KDE desktop: konqueror and not much more. At least you will have that working.

Note: I want to override my old KDE 3.2.0 installation (not enough place on harddrive for two installations).
Read the README files that come with construct. They say how to choose the place were the compiled KDE will be intalled among other things.
