PICMG Configuration
This chapter describes how to configure the DE1B55401 for a Single Board Computer (SBC) with
a PCI interface as defined be the PICMG PCI-ISA interface specification. The DE1B55401can
support an intelligent subsystem on the local bus. The intelligent subsystem is architecture
independent. The 21554 can interface to the PCI interface of any intelligent subsystem. The J101
connector has the capability of accepting an intelligent controller.
