Options for Setting the Gap Count
There are two methods for setting the gap count:
- The RegistryControlUtility (recommended)
- The Windows Registry Editor
There are three gap count options:
- Normal: The gap count is controlled by the MS driver. (Default)
- Automatic: The gap count is controlled by the FirePro driver.
- Manual: The gap count is set by the user.
The FirePro driver (PGR1394.sys) must be installed on your 1394 card(s) for automatic and manual options to work. |
The gap count is maintained through reboots. However, the user must set the gap count every time a new card is installed. |

Using the Windows Registry Editor to Set Gap Count
To access the Windows Registry Editor and change the gap settings:
