SYNOPSIS
ebus* at pci?
DESCRIPTION
TheEBus 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.
