EBUS(4)                 NetBSD Kernel Interfaces 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 tradi-
     tional 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.
