Fixed-Disk Options - IBM RT PC Options Installation

Fixed-Disk Options
The IBM 6150s have one fixed-disk drive installed in drive position C. This
drive is connected to a fixed-disk and diskette drive adapter installed in
adapter slot 1 and to the disk and diskette cable bundle, which are already
installed.
If
you are installing a second drive, use the chart on 2-9 to determine the
correct drive position and installation procedures for the new drive.
If you are installing a third drive, use the chart on 2-10 to determine the
correct drive position and installation procedures for the new drive.
Warning: The fixed-disk drives installed in drive positions C and D
must be the same type drives. Different type drives will not operate
correctly on the same adapter.
The picture below shows the location of the drive type label.
