Dear All, I am trying it now. Its my first experience using sbc board. I feel I am lost now... Normally if we want to install GNU/Linux in desktop or laptop we can use ISO CD or Flash USB for booting and start the installation. Then we can set the partition of harddisk to format where we can put the GNU/Linux OS. Here I found TS 7800 has already preinstalled OS from manufacturer. Should we format it if we want to install emdebian. Riza
