Little Board/486i Technical Manual

Typically, SCSI drives come preset to SCSI ID 0, LUN 0. The “SCSI Initiator ID” option sets the
CPU board’s SCSI Initiator ID. The SCSI Disk Map options are used to specify the ID and LUN of
up to seven SCSI drives. DOS Disk Map options assign SCSI devices as DOS drives. For example, in
a system with one SCSI drive, set SCSI Initiator to 7, SCSI Disk 1 to Id 0, LUN 0, and 1st Hard Disk
to SCSI Disk 1.
2. Drive Partitioning—Reboot the system from a floppy diskette in drive A: containing the operating
system, and run the DOS FDISK utility as described in your DOS documentation. You may be
creating one or multiple partitions, depending on the size of the drive and the partition limitations of
the particular DOS you are using.
3. Final Preparation for System Access—Again, reboot the system from a floppy diskette in drive A:.
What you do next depends on which operating system you use.
DR DOS—Run the DOS SYS command to copy the operating system to the hard disk drive(s) that
you have created in the above steps. Finally, copy anything else you need to the drive(s), and then
reboot the system without the floppy diskette in drive A: to verify that you have installed everything
properly.
PC-DOS or MS-DOS—Use the FORMAT /S command to copy the operating system to the DOS
boot drive (drive C:); or the FORMAT command for drives or drive partitions other than the DOS
boot partition. Finally, copy anything else you need to the drive(s), and then reboot the system
without the floppy diskette in drive A: to verify that you have installed everything properly.

3.13.1 Network Terms
The following are some of the terms used in this section:
! Trunk or network segment—The cable over which network stations communicate. A segment cable
is usually made up of several cable lengths connected together. A segment is limited in its total
length and the number of network stations it can support. However, a network is not limited to one
segment.
! Network trunk —The sum of all the segment cables. Several segments can be interconnected with
repeaters, routers, or bridges to form the network trunk cable.
