Testing and debugging SVR5 NFB drivers

Video configuration testing

Configure your graphic adapter card to verify that it is automatically detected and that all the strings in the grafinfo(DSP/4dsp) file are spelled correctly.

First, configure your graphic adapter to use the highest resolution that is supported by your monitor, using 256 colors. To do this, run the Video Configuration Manager (scoadmin video).

  1. Select Add Adapter. Your graphic adapter should be autodetected.

  2. Select OK.

  3. Select Monitor. Choose a monitor from the list that is displayed. Any monitor should work, assuming that the selected monitor supports the refresh rate, if any, that is specified in your grafinfo file.

  4. Select Resolution. Verify that all resolutions are syntatically correct and that all resolutions are listed. Resolutions should be listed starting with the highest resolution, frequency, and number of colors. The resolutions should decrease first by number of colors, then frequency, and then resolution.

    Configure the highest resolution supported by your monitor at 256 colors.

  5. Select OK.

  6. Select Assign all function keys.

If this is successful, you have configured all screens with your resolution selection. Next, configure vt02 (tty02), to use a different resolution and different color depth. This is used later to verify screen switching.

  1. Select Modify.

  2. Select OK.

  3. Select Add Resolution. Choose a different resolution and a different color depth. For example, if you initially selected 1280x1025 256 colors, select 1024x768 64K colors,

  4. Select Specify function keys.

  5. Select OK.

  6. Select vt02. This configures 1025x768 64K colors on screen vt02 (tty02).

  7. Select OK twice. Note the warning that you are removing the 1280x1024 configuration from this screen.

  8. Continue to select OK until the Video Configuration Manager exits back to the system prompt.
