I couldn't understand your language, but what i can make it from your question is that you are having problem with Installing Oracle8i on a P4 system.
If i am right in guessing your problem, then the problem is you cannot install Oracle 8i on a P4 system, but there is a workaround for it, which is as follows:
1) First dump / copy the contents of the 8i CD on to your Hard disk.
2) Then in the directory where you copied the CD, do a search for a file named "SYMCJIT.dll" and then rename it to "SYMCJIT.dll.ora"
3) Then proceed with your installation.
4) After successfully doing the installation, again rename the SYMCJIT.dll.ori back to its original name as SYMCJIT.dll
