1. Resetting of Windows area
Firstly, you need to modify (reduce) Windows area to secure Linux area.

Please back up your data/files beforehand since the Windows area will be initiallized (HDD recovery).

Use 1CDLinux knoppix for resetting the partition. (With this CD, you can go through the Linux operation.
Very usable if you have one!)
Insert knoppix_v3.8.2-20050505-20050606.iso into USB-CDROM drive and boot the CD with
F12 + power button. Once booted, open console and change the partition with fdisk.

Don't touch /dev/hda2 hidden area! If you destroy it you will never recover your hard drive!!!

#su
#fdisk /dev/hda

and check the current partition with "p".

/dev/hda1 1-6984 7 HPFS/NTFS
/dev/hda2 6985-7296 1c hidden

Leave the recovery area as is and change the XP area from 1-6984 to 10-3000 to
secure the Linux area so that you can create a space for /boot in front, and another space
for Linux installation on back.
Place a boot flag on hda1 and save the updated partition with "w".

/dev/hda1 * 10-3000 HPFS/NTFS
/dev/hda2 6985-7296 1c hidden

Quit knoppix and execute HDD recovery with 0 + power button, then recover the Windows area.
Check if you can start Windows properly.

Now the preparation is done and let's go to FC4 installation!


2. Installing FC4
Boot the FC4-i386-DVD.iso from USB-DVDROM drive.

Installation was went smoothly without problem. I made the disk partition as follows;
/dev/hda1 10-3000 7 HPFS/NTFS
/dev/hda2 6985-7296 1c hidden
/dev/hda3 * 1-9 83 Linux (/boot)
/dev/hda4 3001-6984 5 extended area
/dev/hda5 3001-3100 82 Linux swap
/dev/hda6 3101-6984 83 Linux (/root)

Please don't care even if the assignment order of each area and partition number are mixed up.
Note that if you allocate /boot to hda1 and WinXP to hda2 in order, you will never start Windows!


3. Network configuration
The following process was done after the installation.

[LAN]
Firstly, download the appropriate driver (my case was "install-8_18.tar.bz2") for
Marvell Yukon 88E8053 PCI-E Gigabit Ethernet Controller from the following site.
http://www.syskonnect.com/syskonnect/support/driver/zip/linux/

Secondly, extract the downloaded file with the following command;
#tar xfvj /media/floppy

Then write the following command to start the installation;
#cd Driverinstall
#./install.sh

You will be asked as "choose your favorite installation method:", so enter "1" and then "y"(yes).

The following message will be come out;
kernel header not found
please install the linux header files

Enter the following command to proceed the installation;
#lin -s kernels/2.6.11-1.1369_FC4-i686 linux

Inputting the following command will finalize the driver installation.
#modprobe sk98lin

[Wireless LAN]
Firstlyl, download the below 2 files from the following sites to rebuild SRPM and install
RPM packages;
madwifi-0.0.20050217-1.src.rpm
http://pipiche.free.fr/Downloads/Fedora/SRPMS/
madwifi-kmdl-2.6.11-1.1369_FC4-0.9.4.12-16.rhfc4.at.i686.rpm
http://atrpms.net/dist/fc4/madwifi/

Change directory from /root to /cdrom with the following command;
# cd /media/cdrom

With the following command, RPM packages will be created in /usr/src/redhat/RPMS/i386/;
# rpmbuild --rebuild madwifi-0.0.20050217-1.src.rpm

Inputting the following will complete the RPM packages installation;
# rpm -ivh madwifi-kmdl-2.6.11-1.1369_FC4-0.9.4.12-16.rhfc4.at.i686.rpm
