|
| the control palette register (CPR) to manage and |
|
| update the VGA RAM DAC (Digital Analog |
|
| Converter, a color data storage) of each VGA card |
|
| installed in the system. The snooping process lets |
|
| the CPR send a signal to all the VGA cards so that |
|
| they can update their individual RAM DACs. The |
|
| signal goes through the cards continuously until all |
|
| RAM DACs data has been updated. This allows the |
|
| display of multiple images on the screen. Some |
|
| VGA cards have required settings for this feature. |
