2 * linux/drivers/video/fm2fb.c -- BSC FrameMaster II/Rainbow II frame buffer
5 * Copyright (C) 1998 Steffen A. Mork (linux-dev@morknet.de)
8 * Written for 2.0.x by Steffen A. Mork
27 * The BSC FrameMaster II (or Rainbow II) is a simple very dumb
35 * - PAL/NTSC
36 * - interlaced/non interlaced
37 * - composite sync/sync/sync over green
40 * - 768x576 (PAL)
41 * - 768x480 (NTSC)
53 * At relative address 0x1ffff8 of the frame buffers base address
54 * there exists a control register with the number of
58 * 0 1 0=interlaced/1=non interlaced
59 * 1 2 0=video out disabled/1=video out enabled
60 * 2 4 0=normal mode as jumpered via JP8/1=complement mode
61 * 3 8 0=read onboard ROM/1 normal operation (required)
67 * JP1 interlace selection (1-2 non interlaced/2-3 interlaced)
70 * JP4 modulate composite sync on green output (1-2 composite
71 * sync on green channel/2-3 normal composite sync)
73 * a white screen
74 * JP6 sync creation (1-2 composite sync/2-3 H-sync output)
75 * JP8 video mode (1-2 PAL/2-3 NTSC)
78 * FrameMaster II to a normal TV via SCART connector:
79 * JP1: 2-3
80 * JP4: 2-3
81 * JP6: 2-3
82 * JP8: 1-2 (means PAL for Europe)
89 * to a future X server. Except the pixel clock is really
92 * 9 pin female video connector:
97 * 4 H-sync TTL
98 * 5 V-sync TTL
102 * 9 ground
105 * The FrameMaster II was not designed to display a console
107 * color images. Imagine: When scroll up a text line there
110 * over the slow 16 bit wide Zorro2 bus! A scroll of one
112 * driver - he is at the limit!
