tga - TGA graphics driver
tga* at pci? dev ? function ?
wsdisplay* at tga?
This driver handles TGA graphics hardware within the wscons(4) console
framework.
On TGA adapters, the resolution is set on the card and is
not changed at
runtime. On some TGA models, there are four dip switches.
On other models,
there is a rotary switch with positions 0-F. There are
also some
that use jumpers.

The settings for D, E, and F are for 1600x1200 on some
cards, but there
are no guarantees.
There are also a couple of extra jumpers on some cards. One
of these
jumpers often selects the card to be the primary display.
Exactly one of
the cards in your machine should have that jumper on. If
you have extra
cards, they should have the jumper off.

There are some problems with the background randomly switching between
black and blue.
