   |               MISCELLANEOUS TECHNICAL NOTES                |
   |------------------------------------------------------------|
   | To prevent power interruptions affecting data held in      |
   | controller's cache, it is recommended that you connect an  |
   | attached battery back-up or an uninterruptible power       |
   | supply. Also, terminating drive buses by installing        |
   | on-board resistors is not recommended because the end      |
   | drive on the bus cannot be removed during a "hot swap"     |
   | without leaving the bus unterminated.                      |
