NOTES:
1. AST has determined that the jumper settings shown above
will provide the most reliable operation of the Floppy Disk
drive. This configuration improves the compatibility between
360KB diskettes used in this drive and 360KB drives.
2. CAUTION: Writing from a 1.2 MB drive to a diskette
formatted on a 360KB drive might make the diskette
unreadable on a 360KB drive.
3. When adding a second floppy drive, remove the terminating
resistor "?" from the first drive and reinstall in the
second drive.
