Note: signals above highlighted in light blue are shared between Parallel Port and Floppy Drive
Controller. Depending on BIOS settings, they can assume the first or the second meaning,
respectively for parallel port and for Floppy Disk interface. Depending on the type of Super I/O
controller mounted on the board, however, all signals related to Floppy Disk could be totally
absent. In that case, only signals for Parallel port will be present, and there will be no possibility to
enable internal Floppy Disk controller (see also par.
3.2.2.5 , 4.2 , 4.5.5 and 4.5.7 ).
