   |------------------------------------------------------------|
   |      Note: The ExpressPCI-DC automatically configures its  |
   |      own termination and provides feed back via two LEDs   |
   |      located on the top edge of the card. Exceptions to    |
   |      automatic configuration are listed in the             |
   |      Miscellaneous Technical Notes table.                  |

   |               MISCELLANEOUS TECHNICAL NOTES                |
   |------------------------------------------------------------|
   |      Termination must be manually configured under two     |
   |      conditions. The ExpressPCI-DC will not automatically  |
   |      configure termination when narrow (8-bit) devices are |
   |      attached to the internal connector and wide (16-bit)  |
   |      devices are attached to the external connector, or    |
   |      vice-versa. In these cases, the on-board terminators  |
   |      must be set to terminate high-order byte (the         |
   |      ExpressPCI-DC must lies at the end of the high-order  |
   |      bus). Refer to the ExpressPro-Tools Bus Configuration |
   |      Utilities section in the ExpressPro-Tools User's      |
   |      Manual for appropriate settings. Active termination   |
   |      is strongly recommended.                              |
