These instructions are also available in movie format:

Internal drives are devices that your computer uses to read and store data. You can add or replace drives to your computer to increase storage capacity and to enable your computer to read other types of media such as CD-ROM.
Note: When you install an internal drive, it is important to note what type and size of drive that you can install in each bay. Also, it is important to correctly connect the internal drive cables to the installed drive.

Drive specifications
The 6790 and 6791 computers might come with the following IBM-installed drives:

  • A 3.5-inch diskette drive in bay 1
  • A CD drive or DVD drive in bay 2
  • A 3.5-inch hard disk drive in bay 3
