SYNOPSIS

tga* at pci?
wsdisplay* at tga?

DESCRIPTION

This driver handles DECchip 21030 (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.

TGA Switch Settings

Switch	Pixel	Monitor	Refresh
Setting	Freq (MHz)	Resolution	Rate (MHz)
0	130	1280x1024	72
1	119	1280x1024	66
2	108	1280x1024	60
3	104	1152x900	72
4	93	1152x900	66
5	75	1024x768	70
6	74	1024x768	72
7	69	1024x864	60
8	65	1024x768	60
9	50	800x600	72
A	40	800x600	60
B	32	640x480	72
C	25	640x480	60

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.

BUGS

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