The Planar Board is a PC baby-AT size board providing a low cost entry configuration based on an
industry standard form factor.
The Super I/O Board Video and LAN Adapter
The main system I/O is supplied by means of a single 64-bit PCI adapter (developed by Bull) called
the Video & LAN Adapter. This adapter supports SVGA graphics (Cirrus Logic CL-GD 5436) with 1
MB frame buffer (an optional 1 MB frame buffer is available) and Ethernet 10-Base-T (DEC 21140 or
21040).
The I/O logic is deliberately not native on the motherboard to increase the flexibility for customers,
allowing them to develop or integrate a specific PCI card that best matches their need and application
requirements.
