4. Fixing up things

In the excerpts shown below the -> sign tells you what was modified: do NOT include it in your files!

Monitor entry ( mine is monitors/mfreq/mfreq64.vda)

Board info file ( mine is boards/s3/764-2.xqa , I wonder why they have nearly all the Hercules boards but not MINE: Terminator 64/Dram )

[VISUAL]
    BitsPerPixel   = 8;

    ColorModel     = Indexed;

    [RESOLUTIONS]
    640x480,
    800x600,
    1024x768,
->  1168x876,
    1152x900,
    1280x1024

    [DESKTOPS]
    640x480,
    800x600,
    1024x768,
    1152x900,
->  1168x876,
    1280x1024,
    1600x1200

If the dot clock is low enough ( NOT in this case for my board ) you can put the entry even in the 16bpp and 32bpp sec- tions.

The /etc/Xaccel.ini will look something like this

--------------------------------------------------------------
    Board   = "s3/764-2.xqa";
    Monitor = "mfreq/mfreq64.vda";
    Depth   = 8;
->  Desktop = 1168x876;

    [RESOLUTIONS]
->      1168x876,
        1024x768;

The actual Xinside mode entry in etc/Xtimings

You can check your conversion by running the vgaset program with no parameters while running the Xinside server: it will output an XFree-like line and, if everything went OK, this line will be equal to the line you started from ( except if b and c are equal, I haven't been able to reproduce this situation in Xinside: the best case was c=b+1 ).
