# dino(4)

Dino and Cujo Host/PCI bridges

## NAME

**dino** – Dino and Cujo Host/PCI bridges

## SYNOPSIS

**dino\* at phantomas?** **dino\* at uturn?** **com1 at dino? irq 11** **pci\* at dino?**

## DESCRIPTION

This driver supports Dino and Cujo Host/PCI bridges found on the A, B, C and J-class workstations. Cujo is a 64 bit datapath version of Dino.

On some machines it may also provide an additional serial port through the [com(4)](/com/4.md) driver, or PS/2 keyboard and mouse ports, though the latter are not yet supported.

## SEE ALSO

[com(4)](/com/4.md), [intro(4)](/intro/4.md), [pci(4)](/pci/4.md), [phantomas(4)](/phantomas/4.md), [uturn(4)](/uturn/4.md)

## HISTORY

The **dino** driver appeared in OpenBSD 3.5.

## BUGS

**dino** bridges of revision earlier than three may exhibit data corruption on DMA. This hardware bug does not affect **cujo** or card mode **dino** bridges. See HP Service Note Numbers A4190A-01 and A4191A-01 for more details. Systems affected are those shipped before Aug 20, 1997 and of models: B132L, B160L, C160, C180, C200, C240.
