  <div class="attr SUMMARY">
If the Macintosh Portable internal hard drive is set to a SCSI address<BR>
other than &quot;0&quot;, the Portable CDEV does not operate properly.  The hard<BR>
drive starts up, but the Portable CDEV does not display the &quot;Minutes Until<BR>
Automatic Sleep&quot; option for the hard drive, and the function is disabled.<BR>
This is like starting up the Macintosh Portable with no internal hard<BR>
drive.<BR>
<BR>
Jumpers E1, E2, and E3 on the Conner drives are used to set the SCSI<BR>
address.  They use a binary counting system with E1 the least significant<BR>
bit.  No jumpers across E1, E2, and E3 (the factory setting) sets the<BR>
drive to SCSI address &quot;0&quot;, which is the standard Conner SCSI ID system.<BR>
