1-14 Options Installation
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 applicable system unit diagram in Appendix A. 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
vary in memory capacity, depending on the fixed-disk and diskette
drive adapter used. If you are installing a second or third internal
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 IBM 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.
