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.
