Preface The SBC-MediaGX is a highly integrated Pentium class Single Board Computer. It incorporates all the features found in a standard PC/AT system and has extra support for embedded applications, including additional serial ports, general purpose I/O, flat panel display interface, touch screen interface, silicon disk, Ethernet, and on board audio support.
Whats in the Kit? Arcom's SBC-MediaGX basic kit for QNX v4.25 comprises of the following items:- • A SBC-MediaGX-233-M32-F16 Single Board Computer loaded with a QNX V4.25 image • A power supply with US, UK and EURO style plugs, and power connectors for the SBC-MediaGX board •...
Getting Started This section guides you though the step by step process of connecting up the SBC-MediaGX board for the first time and powering the system to display the 'Photon microGUI' on the display. The SBC-MediaGX is delivered ready to run and there are no link settings or configuration switches that need adjusting to ensure the board will operate.
Task Analysis The following section include three tasks, which take the user through the process of :- 1. Powering up the SBC-MediaGX board 2. Connecting the SBC-MediaGX to a QNX network PC 3. Configuring the SBC-MediaGX board for TCP/IP Page 8...
Note: The default BIOS for the SBC-MediaGX sets the output to ‘CRT only’ mode. If a CRT monitor is detected when the board is switched on. Therefore, to use a flat panel, make sure that a CRT monitor is NOT connected.

Plug the power supply unit into a 100-240V AC power supply If required, press <DEL> to enter the BIOS setup when booting (Refer to the BIOS section in the SBC-MediaGX Technical Manual, supplied on the support CD-ROM for further information.) The system will boot to Photon V1.13 and run Voyager V2.00...
PC and the SBC-MediaGX board, an RJ45 twisted cable has been provided in the development kit On the SBC-MediaGX board, Exit Voyager - Left-click the X in the top right hand corner of the Voyager window On the SBC-MediaGX board, Exit Photon - Left-click the QNX symbol in the bottom left hand corner of the window.

//host_node/.licenses //2/.licenses license -r Installing old style licenses on the SBC-MediaGX board - If there are licenses listed in the '/etc/licenses' directory of your host PC, you must follow these instructions. Otherwise, skip to step 11. Insert license disk into floppy drive on the SBC-MediaGX board, then follow these steps: Fsys.floppy &...
Task 3: Configuring the SBC-MediaGX board for TCP/IP Note: Your system administrator will be able to tell you which IP address, netmask, and gateway address you can use. Please consult this person before proceeding. You may also edit the /etc/netstart file to configure TCP/IP during the boot process.
Reinstalling the QNX Image You can reinstall Arcom’s QNX Image from a QNX Host Machine by creating a network boot disk for the SBC-MediaGX board, or with the bootable support CD. Reinstalling with a bootable CD-ROM Attach CD-ROM drive to SBC-MediaGX board, plug CD-ROM drive cable into socket labelled 'IDE PL22' Insert CD into CD-ROM drive and boot SBC-MediaGX board.
Also, the files will take up at least 8 Meg of available space on the host QNX machine. Creating the network boot disk from Windows Machine: Put Arcom's QNX CD into CD-ROM drive on Windows machine Goto /DOS/DiskImages directory Insert Dos formatted disk into a: drive Double click qnx_net_boot.exe...

On the SBC-MediaGX board, at the prompt type: finit From your SBC-MediaGX board copy the image to the SBC-MediaGX board by typing: fxwrimg /dev/rfd0 //host_node/mediagx.img (It will take approximately 8 minutes to load the image)
Production Image Loading When your development is complete, we suggest setting up your boards for production is as follows. Configure a hard drive with minimal QNX operating system files (see FAQ) and place the following utilities found on the support CD in the /bin directory, to the /bin directory on the hard drive.
Page 21
Format the flash drive: fxfmt /dev/rfd0 Initialise the flash drive: dinit -h /dev/rfd0 Write the flash image to the production board: fxwrimg /dev/rfd0 Image.img After powering down the board, detach the hard drive and reboot. The board should boot and appear the same as the development board. Once a hard drive has been properly configured and you are satisfied with your product you can insert steps 8, 9 and 10 to automatically run from the /etc/config/sysinit file on your hard drive.
Reinstalling the expiring licenses If you are using a network you can install the licenses onto your host node, then copy the file to your SBC-MediaGX board across the network as follows: Place the license disk in the floppy drive of the host node.
Using the SBC-MediaGX If you have followed the 'Getting Started' section you will have a working SBC-MediaGX system. To start developing and using features of the board you will need to refer to the User Manual, which is supplied on the support CD-ROM.
Memory Upgrades The SBC-MediaGX supports a single 168-pin DIMM (Dual In-line Memory Module). If you wish to change the amount of DRAM installed, then you need to source a standard unbuffered 3.3V SDRAM module, which conforms to the PC100 specification. The SBC-MediaGX supports 16MB, 32MB, 64MB and 128MB modules.
The power supply cable is fitted with a 7-way keyed connector. This connects directly to PL12 on the SBC-MediaGX. The keyboard and flat panel display source power from the SBC-MediaGX board. If you are going to add hard disk drives or a CD-ROM into your system it maybe more suitable to use a standard PC/AT compatible supply.
The flat panel display supplied in the development kit is a 6.5" NEC TFT display (NL6448AC20-06). This display has an 18-bit TFT interface and the SBC-MediaGX is configured to drive the correct signals for this display. The standard configuration for the board drives the flat panel interface signals if the CRT monitor is not connected, therefore either can be used during development.
Unsupported Hardware The following hardware is currently unsupported under QNX 4.25 • Realtek 8139 Network Controller - Beta drivers are available from QNX • Audio CODEC - Beta drivers available from QNX • Touchscreen • To receive these beta drivers please contact you local QNX sales office.
