 Boot Procedure 
System BIOS
  The BIOS looks for extensions in the appropriate memory area. The next step is the execution of  the master boot record, which starts a secondary stage loader.
Secondary Stage Loader and Boot Menu
  The secondary stage loader provides the user with a boot menu. The boot option can be selected  by using arrow keys and then made to run by using the enter key. By default, the STC boots into the 
default choice after the specified timeout. You  can then choose between 2 boot options and the 
option of starting the Thin Client in its factory defaults safe mode. 
 
zNormal Boot {Silent Boot  {Verbose Boot 
zSafe Boot 
 
Normal Boot  Silent Boot
  Silent Boot is the standard boot mode; it suppresses all messages from the kernel and starts 
up the graphical desktop. It displays a progress bar along with a text message when major 
checkpoints in the boot process are reached. 
Verbose Boot
  If the Verbose Boot is chosen (by pressing the key F2), the boot messages are shown and 
there will be a detailed display of the boot process and its execution.
Safe Boot
 
If you choose Safe Boot (setup only with standard parameter values), the secondary stage 
loader looks for a bootable system in the flash and continues the boot process as in the other 
boot modes. It basically does booting with a default X-server configuration without the bootsplash 
screen. This method will restore your display settings to default in main boot. This method is very 
useful in case you need to restore corrupted display to restore to the original settings of the 
system. Please beware that all your display related custom settings will get changed.
Networking
  After loading the kernel the network configuration follows. Two different ways can be chosen to  include the terminal in the network environment. According to the settings of the terminal, DHCP 
broadcast or manual configured IP address can be used for this purpose. 
X-Server
  The last step of the boot procedure is the start of the X-Server and the local window manager. Once the boot procedure completes, a desktop will be displayed on the screen as shown below. 
 
 
						

							  
     
 
 
 
 Control Center (Global Settings) 
Starting the Control Center
  Once the STC boots up, you have the option to set the STC as per your choice using the settings 
provided in the Control Panel. The Control Panel can be accessed using two methods. 
 
From the start menu   
Select the Settings option from the Start Menu. You can set up your STC using the options provided 
in the Settings tab. The various setting options provided are  
zDisplay  zInput  zPrinter  zNetwork  zTime  zSystem  zUpgrade  
The following figures demonstrate how to open the Control Panel from the Start Menu. 
zClick on the Start button.  zChoose Settings tab.  zSelect any one of the 7 options (as shown below), to open the Control Panel Settings for the 
particular option selected. 
 
 
Display
  The Display Tab has five options that can be changed.

z8 bit    ( Low Color / 256 Colors)  z16 bit  ( High Color / 65,535 Colors)  z24 bit ( True Color / 16.7 Million Colors)  
Screen Saver 
It can be set to any one of following types with Waiting Time. 
zNone : In this, the screensaver option is disabled. This is the default choice.  zFloating  : In this, a bitmap image is used as the screensaver by making the image to float 
all over on the monitor background once the system is left idle for the specified screensaver 
timeout.  
zMonitor Suspend  : This is the energy saving phase wherein the monitor is left blank once 
the screensaver timeout is exceeded.  
Along with this, you can also set the waiting time before the screen saver is activated. 
Themes 
We can set the theme of the overall system among the three available options. 
zVista Black  zIceBuntu  zWindows Classic                            
Background 
The background can be specified either by specifying wallpaper or letting the theme deciding the 
background color. The wallpaper can be set in three formats.

nents, please refer to your ThinPrint manual.
Network 
 
Network Adaptor  
This menu allows you to configure the network settings for the STC. The available options here 
are 
Network Adaptor
  This drop down menu lists the available Ethernet cards for the STC. By default, eth0 is the 
chosen Ethernet card, but can be changed after the first boot. There is a check box at the 
bottom of the Network Adapter option which can be used to enable or disable the network 
connection.
Setting IP Information 
 zGet IP From DHCP Server :  This option enables the STC to automatically fetch an IP from 
the local DHCP Server connected to it. It automatically sets all the information regarding IP, 
Subnet Mask, Gateway Address and DNS Server IP.  
zSpecify An IP Address :  This option enables you to manually set an IP for your STC. Here 
you have to set the IP Address to be used by the STC, its Subnet Mask and Default Gateway 
address. Apart from these, the Primary DNS Server IP, and if needed, the Secondary DNS 
Server IP, are also required to be set if the STC is supposed to be connected to the internet.  
zOn successful completion of the network activation process, the network activation window 
will be closed on its own and will return to the ControlCenter.  
Setting DNS Server Information 
 zGet DNS Server Address automatically :  This option enables the STC to automatically 
fetch the DNS Server Address from the local DHCP Server connected to it.  
zSpecify DNS Server Address :  This option enables you to manually set the DNS Server Address for your STC. Here you have to manually set the Primary DNS Server IP, and if 
needed, the Secondary DNS Server IP, for Internet access.  
NFS   
NFS (Network File System) enables you to share files via the network. The NFS server exports a 
file system, and the NFS client (Samsung Thin Client) associates this to a mount point of its own 
file system. So afterwards the exported file system will be a logical part of the Samsung Thin 
Clients file system, while it physically remains on server side.  
To set up NFS mount, the server has to be configured first. For detailed information about NFS, 
refer to the corresponding man pages of your server operating system. 
Add NFS Mount
Click Add... to open the Add NFS Mount dialog-box with following options  
zServer: -  Enter the name or the IP address of the NFS server that provides the share.  zDirectory: -  Enter the directory name as it is exported by the NFS server.  zMount Point: -  Specify Mount Point where the NFS shared directory can be mounted 
in local file system of the STC.  
zPermission: -  Enter the permission for the NFS Mount to be Read-Only or 
Read/Write.  
 
						

							 
zSession Name: - Enter the name for the session to be saved or loaded.  zLoad / Save / Delete: -  For loading, saving or deleting a saved session from memory. 
 
 
It is possible to select/create a new/existing mo unt point using the Control Centre dialog boxes 
itself. The process is described here along with figures. 
zFirst the IP address of the NFS server is given.  zIt automatically lists all the directories shared on that NFS server which can be seen like 
this.  
zThen the directory where the share has to be mounted is selected.  zThen a new empty directory is created and named accordingly.   zThen the folder created is selected and then it becomes the new mount point, where the 
NFS share directory will be mounted.

Samba
 
The Samba, or SMB, protocol is very useful because it is used by Microsoft Windows NT, 
Windows 95/98, Windows 2000 and Window XP to share disks and printers. So as Unix 
(including Linux) can also handle this protocol with  the Samba suite tools, it is possible to share 
disks and printers with Windows hosts.  
So it is possible on the Thin Client to mount SMB shares from Windows or Unix Samba hosts. 
The SMB (Server Message Block) protocol is only used for sharing files over the network (no 
printers). It is necessary that the shares you want to mount be created on the Windows or Unix 
host first! 
Add Samba Mount
  Click Add... to open the Add Samba Mount dialog-box with following options  
zServer: -  For a Windows host, the NetBIOS name has to be entered here. In the case of 
a Unix samba host, the host name or IP address is to be entered.  
zUser Name: -  Enter the user name of your account on the Windows or Unix samba host. zPassword: - Enter the password of your account on the Windows or Unix samba host.  zDomain: - Enter domain name of your account on the Windows or Unix samba host.  zDirectory: -  Enter directory name as it is exported by the Windows or Unix samba host.  zMount Point: -  Specify the Mount Point where the share should be mounted in local 
file system of the Thin Client.  
zPermission: -  Enter the permission for Samba Mount to be Read-Only or 
Read/Write, based on the properties of the Samba share provided by the Windows or 
Unix samba host. 
 
 
						

							  
It is possible to select/create a new/existing mo unt point using the Control Centre dialog boxes 
itself. The process is described here along with figures. 
zFirst the IP address of the Samba server is given.  zIt automatically lists all the directories shared on that Samba server which can be seen 
as shown in the figure below.  
zThen the directory where the share has to be mounted is selected.  zThen a new empty directory is created and named accordingly.   zThen the folder created is selected and then it becomes the new mount point, where the 
Samba share directory will be mounted.

Unix samba host.  
Delete Samba Mount
  Click Delete to open the Remove Samba Mount dialog-box with the text message Are you 
sure you want to delete Samba Mount . The following options are provided. 
VNC Server
 
This menu allows you to configure a VNC Server  on the STC from a VNC Client. The available 
options here are 
No authentication
  Enabling this option allows anonymous VNC Client to connect to the Thin Client acting as a 
VNC Server.  
VNC Password Authentication
  Enabling this option allows only authenticated VNC Client to connect to the Thin Client acting 
as a VNC Server. For this, a password has to be set or modified for authentication purpose. 
The Client has to enter this password along with
 proper user name to successfully connect to 
the server. 
 
 
Launch at Startup
  Enabling this option ensures that the Thin Client can act as a VNC Server from the moment 
the OS boots up. 
 
						

							ICA Global Settings 
Citrix® Independent Computing Architecture (ICA)® allows users to connect remotely to servers 
running Citrix MetaFrame. ICA Client offers quick, secure access to applications, content, and 
entire desktops published on servers running MetaFrame. ICA separates the user interface from 
the application while keeping the logic on the server. By doing this, only screen updates, mouse 
clicks and keystrokes traverse the connection media.  
This  ICA Global Settings  section describes how to configure the Global ICA Settings that will 
be valid for all ICA sessions. 
These are the default values for all ICA sessions. Most of these properties (especially color 
depth, resolution and server IP or name) can be altered for each session separately.
Preferences
  The options are self explanatory. 
 
 
Window
  Default Number of Colors
 
You are allowed to set the default number of window colors to 256 (default), thousands (High 
Color) or millions (True Color). The color depth your sessions can run in also depends on your 
Metaframe server. 
Resolution  
Set the default window size by choosing the resolution from the given list. You can also select 
the screen size based on percentage of total screen size or Full screen. 
 
   
Server Location
Server Location 
The Server Location (also called server browsing) provides a method for a network-
connected 
Citrix ICA Client to view a list of all Citrix servers and Published Applications that are 
 
						

							 accessible on the network and using the chosen browsing protocol. 
 
TCP/IP
  If your network configuration uses routers or gateways, or to eliminate additional network 
traffic by the broadcasts, you can set specific server addresses for the Citrix servers from 
which the list of available servers and/or published applications should be requested.
You can place more than one address in the Address List to continue allowing clients to 
connect and function even if one or several of the servers is/are not available.
  TCP/IP + HTTP
  You can also retrieve the information of available Citrix Servers and Published Applications 
across a firewall by using TCP/IP + HTTP server location.
TCP/IP + HTTP server location does not support the Auto-Locate function.
  SSL/TLS + HTTPS
  ISecure Sockets Layer (SSL) and Transport Layer Security (TLS) encryption provide 
server authentication, encryption of data stream and message integrity checks.
If you attempt to make a non-SSL/TLS connection to a SSL/TLS server, you will not be 
connected and a connection failed message will be displayed.
 
Keyboard Shortcuts
  Use the Keyboard Shortcuts page to define alternative key combinations for the common 
hotkeys used within ICA sessions. For example in MS Windows, the key combination + closes 
the current window. It also works within ICA sessions.  
 
  >If you choose to disable the “Alternate switching sequence”, many of these hotkey 
combinations will be occupied by the X Server (esp. +). Therefore you will have to 
use the alternate sequences or map the affected combinations to different ones here to keep 
them available. Any  key combination not used by your X Window manager may still be 
used as usual within the ICA session. 
By default, the key alternatives are mapped to +Function key, but you can 
change the definitions by clicking on the drop-down box “Modifier on Client” and/or “Key on 
Client” of the particular combination. 
If you want to use the PC key combination  during the ICA session, 
use the key combination  or .
Disk Cache
Here you can manipulate the settings for the Bi
tmap Cache. This may considerably improve 
the performance of your ICA session(s) if you ar e working with pictures that are displayed over 
 
						

							 and over again. 
Set the maximum size of local system memory (in kilobytes) to be used for caching and the 
minimum size of bitmaps to be cached and the directory the files should be stored locally. A too high setting might leave the Thin Client with too low memory for its system and other 
applications! In doubt, you have the possibility of adding RAM to your Thin Client.
   
Drive Mapping
 Drive Mapping makes any directory mounted on your Thin Client available to you during ICA 
sessions on Citrix servers. Use this page to specify which folders or drives to map at logon. 
This applies for all ICA connection sessions. 
   
 Activate Drive Mapping
 
This option allows you to temporarily enable/ disable the drive mapping. This gives you the 
advantage of not losing your stored settings, but being able to switch them on/off. 
How to configure a 
“Drive Mapping”: 
Enable one of the three mappings to activate the corresponding entry fields. Then click on the 
corresponding button in the “ Drive to map” column. Now select the drive letter under which 
the local device or folder should be mapped. In case the drive letter you selected is not 
available on the Citrix server anymore, the specified directory or local drive will be mapped to 
the next free drive letter at logon. 
In the “ Local Drive Path” field , set the path name of the local directory the mapping should 
point to. When mapping a locally attached device, use the pre-defined path names as offered 
by the drop-down box. These are the directories the devices are mounted to by default at boot 
up. 
Finally specify the access rights for the mapping. You can choose to grant “ Read Access”, 
“ Write access ” or to “
Ask User ” for each mapping separately. 
The same drive mappings and access settings will apply to all ICA connections.COM Ports
