Use this field to disable or enable the built-in floppy disk drive. You might want

Hard Disk
Leave this value at the default setting Auto.

Normally you can leave this field at the default value DOS, since your notebook is

System Memory and Extended Memory
These two fields are detected automatically at start-up time. Therefore you cannot
highlight these fields and make changes to the values.
