THE CMOS MENU
The Eagle 250 does not use boot ID switches; instead it has a CMOS configuration menu to let you
choose primary and secondary boot devices, as well as set other system options, such as the system
monitor file to use. After installing the AM-138-10, as described later in this document, you can access
the CMOS menu before booting the new computer for the first time. You’ll need to do this if you aren’t
using the default boot configuration. The default settings are:
•
Primary boot device: Disk at SCSI ID 0
•
Secondary boot device: Streamer tape at SCSI ID 3
