The Southland Media Systems (now Quantum 3D) MGX and MGXPlus are SBus color
frame buffers, with graphics acceleration capabilities.
driver interfaces the frame buffer with the
console framework. It
does not provide direct device driver entry points but makes its functions
available via the internal
The MGX and MGXPlus frame buffers will adapt their resolution to the monitor
they are connected to. However, when not connected to a Sun monitor, the
device will default to the
resolution, with a refresh rate of 66Hz. A different resolution can be forced
using the set of DIP switches (sometimes covered by metal foil) located near
the SBus connector on the board itself.
The DIP switch settings are as follows:
All other combinations are unsupported and may damage the hardware.
This driver does not support mode switching at the moment, and drives the card
in PROM-compatible, 8 bit, mode only.
