-The IOC3 is a custom chip developed by SGI.  It's being used in [[IP27|Origin 200]], [[IP27|Origin 2000]], [[IP27|Onyx 2]], [[IP30|Octane]] systems, on a 32-bit [http://en.wikipedia.org/wiki/PCI PCI] card which support [Dual Address Cycle] and on the MENET [[XIO]] card.

 == Functionality ==
 The IOC3 implements the following functionality:
-* 10/100Mbit/s ethernet interface.  An external PHY is required and connected via a standard MII interface.
+* 10/100Mbit/s ethernet interface. An external PHY is required and connected via a standard MII interface.
 * a 486-style secondary bus.  It's usually used to connect a SuperIO chip which contains a 16550 dual port UART.
-* a controller for Dallas Semiconductor (now Maxim) 1-wire bus.  In IP27 systems and on the PCI card a [[NIC]] containing the MAC address is connected to it.  IP30 has several 1-wire devices connected.

 == Limitations ==
-The implementation of the IOC3 PCI configuration space violates the PCI specification severly by only partially decoding the configuration address space.  Only Type&nbsp;0 config cycles are supported.  Only 32-bit accesses to the PCI interface are permitted.  These limitations mean the IOC3 code needs special support in the PCI hostbridge driver.  The card derives internal clocks from the 33MHz PCI clock so it will only work in 33MHz PCI busses.

-The MENET card is an XIO card used in Origin and Octane systems.  Interfacing to the host system via XIO it contains 4 IOC3 chips; 3 of them have serial interfaces connected accessible via 6 mini-DIN serial connectors.
