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.
The development kit has been produced to help customers become
familiar with the board very quickly and provide them with the support
needed to start developing an application right away.
This manual is intended as a guide to enable users to get the
SBC-MediaGX configured and running as soon as possible. The board
supplied in this development kit contains 16Mbytes of flash memory, which
has been pre-configured with the QNX operating system. Once power is
applied to the board it will automatically boot from the on board flash disk
and you will be able to start development.
