Recording Optional Drives and Adapters
This book provides detailed instructions for installing the optional drives
and adapters and for changing the addresses and interrupt levels on the
adapters. The book is written to cover all possible system setups. Because
each system is different, the book cannot tell you, in all cases, the exact slot
for each adapter. The book does provide, however, the possible slots you
can use, depending on the combination of adapters you have.
Unfold the system unit diagram in Appendix A (Figure A-Ion page A-2
or Figure A-2 on page A-3), whichever applies. These diagrams show the
inside of the system units. Before you install the options, you must plan
where to install them and then record their locations. You can then use the
completed diagram as a guide when you install the options.
Read and work through the rest of this section, writing the names of the
drives and adapters on the diagram as you learn where they must be
installed.
Recording Drive Positions For IBM 6150 System Units
When originally purchased, IBM 6150s have one fixed-disk drive installed in
position C. Optional second and third fixed-disk drives may be either 40M
byte or 70M byte, depending on the fixed-disk and diskette drive adapter
used. If you are installing a second or third fixed-disk drive, write the size
of the drive in drive positions D and E on the diagram.
The diskette drive (an IBM Personal Computer AT
®
High Capacity
Diskette Drive) is in drive position A. The second diskette drive can be
either an IBM Personal Computer AT High Capacity Diskette Drive or an
mM personal Computer AT Dual-Sided Diskette Drive.
If
you are
installing a second diskette drive, write the size of the drive in drive position
B.
