NAME
dvbox —
HP98730 DaVinci frame buffer
SYNOPSIS
dvbox* at intio?
dvbox* at dio?
wsdisplay* at dvbox?
DESCRIPTION
The HP98730 and HP98731 are stackable 4-bit color frame buffers, also known as the DaVinci. By adding up to 7 HP98732A frame buffer extensions, it is possible to add overlay planes.
The dvbox driver provides a frame buffer
abstraction to the
wscons(4) console framework.
The DaVinci can be configured at either the ``internal'' address (frame buffer address 0x200000, control register space address 0x560000) or at an external select code less than 32. The hardware installation manual describes the procedure for setting these values.

BUGS
This driver has not been tested with all possible combinations of frame buffer boards and scan boards installed in the device.
