Floppy/Parallel Interface (J10)
The Super I/O controller (W83627HF) provides the floppy controller and the parallel port controller.
The floppy controller and the parallel port controller share the same output connector (J10) on the board
and the device selection is made in the BIOS Setup Utility.
• Floppy Port Controller only supports one floppy drive, in the standard formats, such as 360 kB,
720 kB, 1.2 MB, 1.44 MB, or 2.88 MB drives.
• Parallel Port controller supports standard parallel, Bi-directional, ECP and EPP protocols.
NOTE Due to the multiplexed nature of the signals for the floppy and
parallel ports, you can only connect one of these devices at a time.
Refer to Chapter 4, BIOS Setup Utility later in this manual when
selecting the floppy or parallel device in the BIOS Setup Utility. A
reboot is necessary for the change of BIOS settings to take affect.
Table 3-7 describes the floppy/parallel port (J10) pin/signals with 26-pins, 2 rows, consecutive (1, 14)
with 2 mm pin spacing.
Table 3-7. Floppy/Parallel Interface Pin/Signal Descriptions (J10)
Pin # Signal Description
1Strobe*
Parallel Strobe* – This is an output signal used to strobe data into the printer.
I/O pin in ECP/EPP mode.
2PD0
INDEX*
Parallel Port Data 0 – These pins (0 to 7) provide parallel port data signals.
Floppy Index – Detects head positioned over the beginning of a track.
3PD1
TRK0*
Parallel Port Data 1 – See pin-2 (PD0) for more information.
Floppy Track 0 – Detects when head is positioned over track 0.
4PD2
WPRT*
Parallel Port Data 2 – See pin-2 (PD0) for more information.
Floppy Write Protect – Senses if diskette is write protected.
5PD3
RDATA*
Parallel Port Data 3 – See pin-2 (PD0) for more information.
Floppy Read Data – Raw serial bit stream from the drive for read operations.
6PD4
DSKCHG*
Parallel Port Data 4 – See pin-2 (PD0) for more information.
Floppy Disk Change – Senses when drive door is open or the diskette has been
changed since the last drive selection.
7 PD5 Parallel Port Data 5 – See pin-2 (PD0) for more information.
8 PD6 Parallel Port Data 6 – See pin-2 (PD0) for more information.
9 PD7 Parallel Port Data 7 – See pin-2 (PD0) for more information.
10 ACK*
DS1*
Parallel Acknowledge * – This is a status output signal from the printer. A Low
State indicates it has received the data and is ready to accept new data.
Floppy Drive Select 1 – Select drive 1.
11 BUSY
MTR1*
Parallel Busy – This is a status output signal from the printer. A High State
indicates the printer is not ready to accept data.
Floppy Motor Control 1 – Select motor on drive 1.
12 PE
WDATA*
Parallel Paper End – This is a status output signal from the printer. A High
State indicates it is out of paper.
Floppy Write Data – Encoded data to the drive for write operations.
