### 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.
