.Sh INTRODUCTION
|
|
.Nm
|
|
is a I/O interconnect bus mostly found in
|
|
.Tm SPARC
|
|
workstations and small to medium server class systems. It supports both
|
|
on-board peripherals and extension boards. The
|
|
.Nm
|
|
specifications define the bus protocol as well as the electrical and
|
|
mechanical properties of the extension slots.
