1 README for project LILO / images
2 ================================
4 Picture files for boot menu must be rl-coded bmp files.
6 Files as distributed have been edited through 'lilo -E XXXX.bmp' to specify
7 useful boot table layouts, colors, and timer positions. The companion *.dat
8 files contain photo credits, where applicable, as well as the 'lilo -E ...'
9 parametric information contained in the LILO-bmp headers in the actual
13 "16c" in the name indicates 640 x 480 x 4bit with 16 colors (mode 0x12)
14 "256c" in the name indicates 640 x 480 x 8bit with 256 colors (mode 0x101)
16 *16c* files will display on any IBM-compatible VGA display adapter.
17 *256c* files require a video adapter which supports VESA bios extensions;
18 specifically, mode 0x101 -- 640 x 480 x 256 colors.
20 If you have booted with LILO, then you may easily inquire of your video
21 adapter's capabilities with:
25 The video adapter type, and the video modes supported by its BIOS, will be
26 displayed; i.e., those graphic modes of interest to the LILO bitmap
29 Creating image for background
30 -----------------------------
32 With ImageMagick you can use the convert command as follows:
34 for images with 16 colors:
36 convert -verbose "$INFILE" \
37 -resize 640x480 -density 72x72 -depth 4 -colors 16 \
38 -colorspace RGB -compress RunlengthEncoded "$OUTFILE"
40 for images with 256 colors:
42 convert -verbose "$INFILE" \
43 -resize 640x480 -density 72x72 -depth 8 -colors 256 \
44 -colorspace RGB -compress RunlengthEncoded "$OUTFILE"
46 Note: the Runlength-Encoding (RLE) will be made better by Gimp.
49 Example for syntax and colors
50 -----------------------------
52 color palette: 0 black, 3 magenta, 7 pink,
53 8 middle grey, 10 bright grey, 13 white
55 bmp-table = <x>,<y>;<ncol>,<nrow>,<xsep>,<spill>
56 if <ncol> = 1 then there are only one menu column
57 and <spill> will not be defined
59 bmp-colors = <fg>,<bg>,<sh>;<high-fg>,<high-bg>,<high-sh>
60 if <bg> or <high-bg> not defined, than it is transparent
61 if <sh> or <high-sh> not defined, than it is no color
63 bmp-timer = <x>,<y>;<fg>,<bg>,<sh>
