4. Desktop Operating Environment
4.1 The X-Desktop Screen
By default, in this very first boot operation, it will allow the DHCP process to be in effect. This
means that you’ll need to have the LAN/WLAN connection physically established and the
presence of DHCP server in your environment. The boot operation will take some time to timeout
if otherwise.
At the end of the boot operation, the TC will lead you to the screen below and will be referred to
X-Desktop hereafter. This X-Desktop is your operating environment through out this
documentation. And your further usages of TC product will start from here. There are two modes
of X-Desktop operations: User and Safe modes.
Figure 4-1: The X-Desktop User Mode Screen

TC Administrator Guide

Figure 4-2: The X-Desktop Safe Mode Screen
4.2 User mode Operations
The above figure 4-1 is the X-Desktop operation in User mode. This is the operation that the end
user will be involved. And depend on various configurations and settings, this user mode
X-Desktop can contain whatever operations the administrator think appropriate for the end user.
It can contain nothing and connect to the server for running certain server based application there.
Or it can contain lots of different kind of applications such as browser, media player, CD player and
etc.
It’s our design philosophy of this product that this product should appear as simple as possible for
the end users. And the administrator can take full control of the TC components in either local or
remote management.
4.3 Safe mode Operations
The Safe mode operation of the X-Desktop, as in figure 4-2, is for the administrator to do various
configurations or other advanced selections for this product and for this user.
To enter the Safe mode, you can restart the system again and press keys Ctrl+Alt+BackSpace
when you see the boot screen as indicated in Figure 3-3. This operation will lead the TC into Safe
Mode for further operation. You’ll be prompted to enter the username Administrator and
password 123 for this mode. The figure below is the X-Desktop in Safe mode.

TC Administrator Guide
11
The administrator is encouraged to enter this mode for further configurations next.
4.4 Backup and Restore the settings
The configuration settings that you made can further be backed up to the connected and detected
device, such as HDD, Floppy disk or USB Disk. Later on, the setting files can be restored back to
the system. The administrator needs to click on the Safemode →Setting →Backup/Restore
Settings. The resulting file is in the ./setting/bk.tar.gz in your connected local /mnt/c, /mnt/floppy or
/mnt/usb-disk device.
The figure below shows the screen of above operation.

5. Local Administration
This chapter describes the local configurations that the administrator can choose to perform for
particular TC PC on site. Although, this kind of operations are not really necessary but considered
to be most direct and effective way when various advanced administration methods are not in
operations. (Please refer to relevant chapters for Central Administrations if large site installation is
under concerns.)
5.1 Default TC Configurations
The default configurations of the product are as followings and if the administrator chooses to use
otherwise then further sections can be of help in doing so.
The administrator needs to enter the safe mode to do any further
configurations. The password is with 123 when in safe mode.
It will require performing the “Load Driver CD” operation for the first
time.

servers in priority sequences:
DHCP-FTP: Your local ftp server is running and when the DHCP server
with root path information is enabled. Then the anonymous access
is used to get the global.ini and username.ini from this ftp server.
To read in the pre-configured global.ini. This situation is true when
above steps are in effect and DHCP/DNS servers are in operations.
And if no physical Internet connection to read in the global.ini
then the default settings in TC will be in used.
User’s Desktop: All options disabled except the toolbar and the shutdown
options.
Resources: All options enabled except the floppy.
Boot Menu: Disabled. When enabled, during the boot process, the user can
choose to boot from local hard disk or the DOM during 5 seconds period.
