Step by step guide install CentOS 5.5 with network install

New class has started and I try to give my student new experince. During my search I found new thing that I think they like to try. Network installation would be good for next lesson. I ever try it few years ago with Linux Mandrake. Create diskette boot and perform installation from network server where all required files has already copied.

Nowadays, its rare to see computer with floppy disk as slowly replaced by usb flash disk. Ok, I decide to try install CentOS 5.5 with network install mode.

Here the steps :

Download CentOS 5.5  iso file
