PNP IO Port 0xA79
This setting allows the Plug-N-Play configuration address to be mapped to the
PC/104 bus. The I/O space above 0x400 is mapped to the PCI bus by default. If a Plug-N-Play device is
connected to the PC/104 bus change this setting to ‘GP Bus’.

The Shadow Configuration menu allows BIOS extension ROMs to be copied to SDRAM in upper
memory regions to reduce access times. Execution directly from ROM is significantly slower than
executing from SDRAM. The region from C000-C7FF is usually reserved for the video BIOS extension in
a PC compatible system, shadowing is enabled to optimize the video BIOS functions. The region from
E000-FFFF contains the embedded BIOS code in the TS-5500. This region is shadowed to optimize
BIOS code execution and to allow reprogramming of the BIOS while the BIOS is executing out of
SDRAM. Other regions can be shadowed as required by specific applications.
