Installing files from option diskettes
An optional device or adapter might come with a diskette. Diskettes that
are included in option packages usually contain files that the system needs
for recognizing and activating the options. Until you install the necessary
files, the new device or adapter might cause error messages.
If your optional device or adapter comes with a diskette, you might need to
install some configuration (.CFG) files or diagnostic files (.EXE or .COM)
from the diskette to your hard disk. See the documentation that comes
with the option to determine if you need to install files.
