SCSI ID Setting
SCSI ID settings are made through DIP switches located on the SCSI board.
Each SCSI board IDSEL switch has default settings as labeled below. The
default settings were set for use with a 2-channel SCSI card. Each channel
may repeat the SCSI ID numbers of another channel. Make sure that each
IDSEL switch (on each channel) has its own unique setting if making changes
to these switches. See next page for more information on SCSI ID settings.
