  hard disk is jumpered in Write Protect mode.  
- Boots to Installation Abort when 2 or more drives fail to start up.
- The controller now attempts a synchronous negotiation with synchronous capable

- Corrects possible incorrect data that could be passed to the calling

  (8k or 64k) with Read Ahead turned on while doing a sequential read during an 
  OFFLINE drive.
- A change made to begin Background Initialization on the next write operation 
  following a configuration update.
