EBUS(4)                      Device Drivers Manual                     EBUS(4)

NAME
     EBus - introduction to SPARC EBus bus support and drivers

SYNOPSIS
     ebus* at pci?

DESCRIPTION
     The EBus bus is designed to provide the ability to put ISA and
     traditional Intel-style peripherals in a SPARC based system with a
     minimal amount of glue logic.  Typically, it is implemented in the PCIO
     IC from SME, which also implements a hme(4) compatible PCI network device
     (`network').  The EBus has four DMA channels, similar to the DMA seen in
     the esp(4) SCSI DMA.
