CentOS Net Install
From KlavoWiki
Download the 10 MB net install ISO image and boot from the CD. Configure the appropriate IP settings and select HTTP install or URL for CenOS 6.0.
For Cent OS 6.0 and onward installs, the format is slightly different. The Net Install CD is 200 MB and not 10 MB and the required path is prefixed with http:// or ftp:// with the full path. The URL and Folder are no longer separated.
I typically install from USB and not DVD anymore. To send an ISO to USB use iso2usb.
