Trouble with Floppy Disks
Why can't I use a floppy disk?Confirm the external floppy disk drive is connected and the disk is inserted correctly. The disk may be unformatted, corrupted, or write-protected. Check the write-protect tab. Ensure the disk is not full. Verify 'Diskette A:' is set to 1.44MB, 31/2 in the Setup Utility. Check for supervisor password restrictions.
