# 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.
