OOps, typo there..
PXE boot, and yes, same as network boot..
Clicking KDE Desktop will give you a full KDE desktop.. Bear in mind, the system booted via lan, so you'll have to mount your HD locally unless the system recognises it and does that for you...
so FULL KDE via NETWORK BOOT, NOT off HD,
(apps can be installed to hard drive l8r..)
KDE has desktops in the bottom right of your screen. When you start KDE, you'll see what I mean...
to get back to the MD, simply click the 5th icon, the one with the big X in it... LOL
