System Hardware

The Silicon Graphics Indigo(TM), Indigo 2(TM), Indy(TM), Crimson(TM), CHALLENGE(TM)/Onyx(TM), and POWER CHALLENGE(TM)/POWER Onyx(TM) families of workstations and servers may contain the following hardware components:

One or more MIPS® RISC CPUs
Local memory bus
Zero or more VME-bus adapters
Zero or more EISA-bus adapters
One or more SCSI-bus adapters
Zero or more GIO-bus adapters

Although each Silicon Graphics system provides a similar architectural interface, there are some hardware-specific differences that affect how you write a device driver. Most of this guide discusses only those features that are common to all systems. For a description of hardware-specific differences, see Appendix A, "System-specific Issues" (which also describes how to write drivers that work correctly across all Silicon Graphics systems).
