12 This device acts as an adapter between the
14 framework and the Amiga custom chip driver functions.
15 It exports the internal
17 interface and contains the necessary rendering functions to
18 operate a text terminal with virtual screens. It uses the
19 Amiga abstract graphic driver (grfabs) functions for the low-level
22 Currently it does not support running X.
23 It can however coexist well enough with grf0 to make possible running
24 X the old way, but be warned, you cannot switch screens while
25 in X and when quitting it, it seems to hang. Switching a screen
26 then will bring up the text console. As always, we apologise for
29 What it does support is hilite (bold), underline, reverse and
30 foreground/background colors.
31 .Ss Virtual terminals and screen types
32 The number of virtual screens is limited only by
33 the available chip memory.
35 Each virtual screen can have a different screen type.
36 A screen type defines the following things: height and width
37 in pixels, number of colors, and font size.
38 The supported screen types are listed below.
39 .Bl -bullet -offset indent -compact
41 80x64 - display size 640x512 with 8 colors, font size 8x8
43 80x51 - display size 640x510 with 8 colors, font size 8x10
45 80x50 - display size 640x400 with 8 colors, font size 8x8
47 80x40 - display size 640x400 with 8 colors, font size 8x10
49 80x32 - display size 640x512 with 8 colors, font size 8x16
51 80x31 - display size 640x248 with 8 colors, font size 8x8
53 80x25 - display size 640x400 with 8 colors, font size 8x16
55 80x24 - display size 640x192 with 8 colors, font size 8x8
57 default - same as either 80x64 or 80x50, depending on the presence
58 of GRF_NTSC and GRF_PAL in the kernel configuration.
61 The grfabs code determines the actual screen mode that is used.
62 The config options GRF_NTSC, GRF_PAL, GRF_AGA, etc. determine
63 what kind of chipsets/modes are available.
65 Fonts of width 8 and any height are supported.
66 Fonts can be compiled into the kernel by specifying "options FONT_[fontname]"
67 in the configuration file, or loaded with the
