The following is a brief procedure you can use to prepare a SCSI hard disk drive for use with
DOS:
4. Setting the SCSI Device ID’s – using the options in SETUP’s Extended SCSI and “Hard
Disk Configuration” menu, specify the appropriate SCSI device ID’s for both the drive
(must match jumpers on the drive or drive controller) and the Ampro Little Board/286.
Normally, you will want to set the Ampro Little Board/286 to SCSI ID 7 so that a SCSI bus
Reset will be issued on system powerup or reset. Typically, SCSI drives come preset to
SCSI ID 0, LUN 0. The “SCSI Initiator ID” option sets the CPU board’s SCSI Initiator ID;
“SCSI Disk Map” options are used to specify the ID and LUN of up to seven SCSI drives;
“DOS Disk Map” options designate one or more SCSI devices for access by DOS. For
example, in a system with one SCSI drive, you will probably set “SCSI Initiator” to “7”,
“SCSI Disk 1” to “Id 0, Lun 0”, and “1
st
Hard Disk” to “SCSI Disk 1”.
4. “Low Level” Formatting – The low level format erases all data from the drive and
prepares it for use. In many cases, the low level format function eliminates bad blocks from
the usable area of the drive, by using spare blocks to replace bad ones. Most embedded
SCSI drives are factory formatted. However, it is best to perform a low level format prior to
using a drive for the first time. Use the Ampro SCSIFMT utility to perform the low level
format of the drive. The drive must be SCSI Common Command Set (“CCS”) compatible,
to be formatted by the SCSIFMT utility.
4. Drive Partitioning – Reboot the system from a floppy diskette in drive A containing the
operating system, and run the DOS FDISK utility in the manner 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.
4. Final Preparation for System Access – Again, reboot the system from a floppy diskette in
drive A. What you do next varies, depending on what operating system you are using.
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
everything has been installed 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, in case of 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
everything has been installed properly.
