SPARC SBus Expansion Subsystem

## NAME

**xbox** – SPARC SBus Expansion Subsystem

## SYNOPSIS

**xbox\*   at sbus?** **sbus\*   at xbox?**

## DESCRIPTION

The **xbox** driver provides support for the Sun SBus Expansion Subsystem. This device consists of an SBus card and a chassis which has three additional SBus slots.

## SEE ALSO

[intro(4)](/intro/4.md), [sbus(4)](/sbus/4.md)

## BUGS

DMA support through **xbox** is currently not implemented. This means that SBus devices using DMA (such as SCSI and some Ethernet controllers) will not attach correctly, and will not work.
