J1 and J2 for the ISA Bus
The ISA BUS
Connectors J1 and J2 carry the signals for the ISA Bus. These signals match definitions of the
IEEE P996 standard. Below is shown a picture of the ISA BUS
Figure 4. ISA BUS layout
According to PC/104 specifications, KEYs are filled holes in the upper side and missing pins in
the lower side of the bus connector. This is made to avoid the wrong insertion in/of another
module.
For further info about ISA (PC/104) bus, please refer to the PC/104 Consortium Web
site at www.pc104.org
.
How to connect to the CPU other PC/104 & PC/104 devices: the stack
assembly
The ISA Bus connectors of the module are designed to allow the connection onto a stack of other
PC/104 and/or PC/104Plus devices. We recommend you to follow the procedure below ensuring
that stacking of the modules does not damage connectors or electronics parts.
1. Turn off power to the PC/104 system or stack.
2. Select and install standoffs to properly position the module on the PC/104 stack.
3. Touch a grounded metal part of the rack to discharge any accumulation of static electricity.
4. Remove the module from its anti-static bag.
5. Check that keying pins in the bus connector are properly positioned.
6. Check the stacking order; make sure an XT bus card will not be placed between two AT bus
cards or it will interrupt the AT bus signals.
7. Hold the module by its edges and orient it so that the bus connector pins line up with the
matching connector on the stack.
15
8. Press evenly the module onto the PC/104 stack.
The picture below shows a typical module stack with 2 PC/104 modules, 1 PC/104 16-BIT
module, and 1 PC/104 8-BIT module.
The maximum configuration for the PCI bus of PC/104 modules is 4 plus the Host Board.
If standard PC/104 modules are used in the stack, they must be the top module(s) because they
will normally not include the PCI bus.

Figure 5. The Module Stack
Do not force the module onto the stack! Wiggling the module or applying too much
pressure may damage it. If the module does not readily press into place, remove it,
check for bent pins or out-of-place keying pins, and try again.

This section of the connector implements the following functions:
Keyboard
An AT compatible keyboard can be connected to the module through connector J3. The
following table lists the pin-out of connector J3.
System reset
Connecting the pin 3 of the multifunction connector to ground performs a hardware reset
of the module. It is possible to use an external push-button, normally open. J3 provides a
connection for an external normally-open pushbutton to manually reset the system.
Connect the other side of the switch to ground. The reset signal is “de-bounced” on the
board.
External Battery
Pin 9 of the multifunction connector allows the connection of an external backup battery
(typically from 3 to 3.9 V). This battery is used at power down to preserve the date-time in
the Real Time Clock.
The typical battery consumption with the module off is 7 uA.

Speaker
A transistor to supply 0.1 watt of power to an external speaker controls these outputs. A
transistor amplifier buffers the speaker signal. Use a small general purpose 2 or 3-inch
permanent magnet speaker with an 8-ohm voice coil.

The audio output is based on two signals: one come from the output of Timer 2, and the
other come from I/O port 61h compliant with the AT Standard.
Power button
If the soft power management is enabled, a low signal in the pin10 turns the system on or
off.

This signal is defined by bit 0 of the UART Modem Control Register (MCR) and the bi-
directional line is controlled as follows:
25
- bit 0 of the MCR register = 0 means RS485 line receiving
- bit 0 of the MCR register = 1 means RS485 line transmitting
The I/O address of the MCR is "Serial port Base address"+4H.
See Chapter 4 for info about the Serial ports configuration.

Note: during the floppy disk assignment it is a good practice filling the devices consecutively,
without any “hole” from one device to another.
Note: when the boot sequence starts from floppy disk number one (DOS letter “A”), any device
selected as
floppy disk 1 can be a bootable disk. Obviously this device must represent a real
bootable disk, with a proper boot sector and containing a valid O.S.
Note: In the SpacePC 1232 only one external FDD can be connected.

Error Handling Page
Generally, in a normal desktop BIOS, when an error is encountered by the POST sequence, the
bootstrap stops and waits for a reboot. For example a simple keyboard ab sence represents an
irrecoverable error. This can be a serious problem in embedded systems. Using the
Handling page, the user can decide to ignore one or more of errors that could be encounte re d
during the boot.

Chapter 5 How to update the BIOS. The SSD
This chapter explains how to use the BTOOL Program and gives information about the Integrated
Solid State Disk.
Warning: The BTOOL Program can be different for each CPU and each BIOS version.
For the last versions visit the site: www.parvus.com.
57
How to update the BIOS: the BTOOL Program
The BTOOL program is a utility used to program the BIOS (that is stored in the Flash EPROM) in
the following cases:
¾ BIOS upgrade;
¾ Installation of a MiniDOS compatible program into the Flash (Integrated SSD);
¾ Installation of a BIOS Extension into the Flash.
PLEASE NOTE:
BTOOL program must be run under MS-DOS environment, not DOS WINDOW, (so, if it
is necessary, create a bootable floppy disk, with the command FORMAT/S. The diskette
must be formatted as a 1.44 MB disk.).
Power supply must be assured during all the program execution.
Please run AUTOEXEC.BAT and CONFIG.SYS without any parameters!
Please don’t run any memory manager. If HIMEM.SYS or EMM386 are running, the
BTOOL program doesn’t work!
It will be useful if the BTOOL program is stored in a Floppy Disk (for example in the bootable disk)
The program must be run using the
The on line help, with the available options will be displayed, as follow:
BTOOL (or BTOOL.EXE) command line at the DOS prompt.
58
59
OPTIONS EXPLANATION
BTOOL /S This option runs the Setup program without the necessity of rebooting
the system and then pressing “F2”
BTOO L/L This option locks the setup. In this way the access to the Setup
Program is denied.
BTOOL /U This option unlocks the setup. In this way the access to the Setup
Program is re-established.
BTOOL /G FILENAME (*) This option gets the Setup Data from the system and save it in a file
with the name “FILENAME.BIN”.
BTOOL /P FILENAME (*) This option reads the Setup Data from the file named
“FILENAME.BIN” and put it in the system
BTOOL /B FILENAME (*) This option updates the entire BIOS firmware with the version stored
in the file named “FILENAME.BIN”; for example BIOS.BIN, stored on
a floppy.
BTOOL /V FILENAME (*) This option updates only the video BIOS firmware with the new
version stored in the file named “FILENAME.BIN”
BTOOL /U FILENAME (*) This option updates the Emergency BIOS Firmware with the new
version stored in the file: “FILENAME.BIN” (this option is not used in
the SpacePC 1232)
BTOOL /DA This option creates the image of the Floppy “A:” in the Integrated SSD
BTOOL /DB This option creates the image of the Floppy “B:” in the Integrated SSD
(*): all these files are in binary (.BIN) format
The BTOOL program always ends with a module’s hardware reset (pressing
CTRL+ALT+DEL is not enough). It is necessary to switch off and then switch on the
CPU in order that the changes take effect.
EXAMPLE: Update the BIOS
For the BIOS files and for upgrades, visit www.parvus.com. It is very useful to store
the new BIOS version in a floppy disk.
¾
Before proceeding, you have to be running DOS (or ROM-DOS) environment without any
memory manager
¾ Type the following command at the DOS prompt and press “ENTER”:
A:\>BTOOL /B BIOS.BIN (*) (*) The file name can be different according to technical
needs.
59
¾ The program will store the new BIOS version.
¾ Follow all the instructions the BTOOL gives you
¾ BTOOL will inform you about the results of the operation,
¾ Power off and then power on the CPU module.
The Integrated Solid State Disk
A portion of the Flash EPROM can be used as an Integrated SSD. This Integrated SSD is like a
write-protected floppy disk for storing files.
In the SpacePC 1232, the portion is 768 KB, and before enabling it needs to be written-to using
the
BTOOL program.
Then it is possible to copy data from a real floppy disk.
EXAMPLE: Create an image of a floppy disk into the Integrated SSD
¾ The internal Solid State Disk can be either enabled or disabled in the Setup (Floppy Disk
1..4).
¾ Before proceeding, you have to format a new floppy disk, with the command FORMAT/U (or
FORMAT/S if you want to create a bootable floppy).
¾ Create the “image disk” copying into the diskette all the files and the directories you need.
During this copying process
create empty sectors that will be mirror-like stored into the SSD, wasting space.
don’t delete any file/data on the floppy, because this will
Restart over again with the format procedure if you have any troubles or mistakes occur.
Data stored on floppy mustn’t go above 640 KB (which is the effective Flash size
dedicated to be used as Solid State Disk).
¾ Type the following command at the DOS prompt:
A:\>BTOOL /D A (BTOOL /D B)
¾
The program will ask you to insert the “image disk” in drive A (or B).
¾ Follow all the instructions the BTOOL gives you: the program will proceed by erasing the
Flash device blocks and then wr iting and verifying them with the data present on the “image
disk”.
¾ BTOOL will inform you about the results of the operation. If everything is ok and if you have
already enabled the SSD please reset the system with CTRL+ALT+DEL. If you haven’t
enabled the SSD before, you can use the Setup Program to enable the Solid State Disk; quit
the Setup Program saving data to EEPROM (in this case, rebooting the system with
CTRL+ALT+DEL is not necessary).

Chapter 6 Virtual Peripherals
This chapter describes how to control the SpacePC 1232 module directly from a Laptop or a
standard PC compatible computer:
Use this mode when the PC/104 system doesn’t have I/O devices connected to it.
The “Virtual Peripherals” mode
The SpacePC 1232 module is designed to be used in industrial environments as a stand-alone
module, independent from specific peripherals. Nevertheless, it might become necessary, for
operation or maintenance, to interface the module with I/O devices: keyboard, monitor, and floppy
disk.
The SpacePC 1232 module can operate in a specific modality, called “Virtual Peripheral” mode.
Thanks to this modality the CPU can use the peripherals of another PC compatible computer
(called Host computer), which are not directly connected to the module’s PC/104 bus.
To enable this modality, the SpacePC 1232 module must be connected to the Host computer
through a serial port or a parallel port, and the VP program must run on the Host computer. In
“Virtual Peripheral” mode, the operator runs with the SpacePC 1232 module using the I/O devices
of the PC or AT compatible computer. The PC’s I/O are redirected on a serial (or parallel) line.
61
Local and redirected peripherals
In “Virtual Peripherals” mode, two types of peripherals are used:
¾ The peripheral directly connected to the module (keyboard, video interface, SSD and floppy)
named “local peripherals”
¾ The Host computer’s peripherals used for the remote control of the module (keyboard, video
interface and Floppy) named “remote or redirected peripheral”.
You can select which remote peripherals are redirected in your VP connection: all the Host
computer’s peripherals or only some of them.
“Virtual Peripherals” connection
To perform the “Virtual Peripheral” connection, you need the following items:
¾ The CPU module with power supply and one free serial/parallel port;
¾ The Utility Disk (CD-ROM) provided with the SpacePC 1232 module;
¾ A PC or AT compatible computer (the Host computer) with a serial port working at 115Kbaud,
or a parallel bi-directional port and
Win95/98/2000!);
¾ A VP cable (parallel or serial cable). Parvus doesn’t supply any VP cable. You must make
it according to the tables on the following pages. If you are using a serial cable, you must
make a VP adjustment (as described in the following figure) in it.
provided between the RTS and CTS (or DTR and RI) signals on the end facing the
Multifunction cable;
The Virtual Peripherals connection can be performed as follows:
¾ Connect the Host computer to the SpacePC 1232 module through the parallel port or
through the serial port using the multifunction cable and the VP cable. Turn on the Host
computer
¾ Run the VP2000.EXE program on the Host computer
¾ Turn on the CPU

If you select the [/V] [/K] [/D] [/C] parameters, the VP connection will be performed according to
the following rules:
¾ Only the selected remote peripherals are redirected in VP connection.
¾ The local peripherals connected are used according to the setup.
¾ If the floppy disks are redirected, it is not possible to use the local Host computer floppy for
PC operations.
¾ The Boot is performed from the selected peripheral.
From now on, the host computer's peripherals selected are at the disposal of the SpacePC 1232
module. It is now possible to boot from the host computer's floppy disk/CD-ROM, or to debug a
program and edit files using the host computer's peripherals.
Pressing the “printscreen” key will terminate the VP2000 program returning the CPU
module to DOS.
To re-connect the SpacePC 1232 module to the host computer, run the VP2000.EXE program
again.
This message will appear:

Chapter 7 Watchdog Timer
This chapter describes the configuration of the Watchdog Timer with some examples.
The watch dog is a part of the on–board SUPER I/O device SMSC FDC 37B782
The Super I/0 watchdog allows managing time-outs in order to seconds or minutes (depending on
the Super I/O programming).
66
67
Watchdog modalities
The watchdog function resets the board at the end of the countdown.
There are two ways to program the watchdog:
• Using BIOS INT 52h
Using direct Super I/O registers programming
•
BIOS INT 52h - functions 0Ch, 0Dh, 0Eh
This method can be used under DOS or under Operating Systems using the board BIOS (i.e. not
under Linux which erases the BIOS after the boot and autonomously manage the module
hardware).
The functions implemented from the BIOS are:
INT 52h, function 0Ch: watchdog enabling with a fixed time of 2 seconds. This function programs
and starts immediately the watchdog counter.
INT 52h, function 0Dh: watchdog erasing. Counting is interrupted and watchdog disabled.
INT 52h, function 0Eh: watchdog refresh. Every call to this function restarts the counting from the
initial value.
When the watchdog is activated, the countdown starts immediately. If no refresh occurs, when
the default timeout expires, the board reset is executed. So the watchdog must be enabled and
continuously refreshed, avoiding in this way the board reset.
Example:
...
MOV AH, 0Ch
INT 52h ; Enable the watchdog (fixed timeout = 2 seconds)
...
Super I/O registers programming
This method must be used when the OS doesn’t manage the BIOS (i.e. Linux) or when a
personalized watchdog programming is required.
The following example shows how to change the Super I/O (SPIO)
registers:
; SPIO: enter in configuration mode ...
MOV DX, 03F0h ; SPIO Index Port
67
FDC 37B782 watchdog

OUT DX, AL ; Select the Logical Device 8
; Select the time base (seconds or minutes) ...
MOV DX, 3F0h ; SPIO Index Port
MOV AL, F1h ; Watchdog timer units register (WDT_UNITS)
OUT DX, AL ; Point to register WDT_UNITS
INC DX ; SPIO Data Port
IN AL, DX ; Read WDT_UNITS
OR AL, 01h ; Mask reserved bits and set time in seconds
; AND AL, FEh ; Mask reserved bits and set time in minutes
MOV BL, AL ; Save new WDT_UNITS value
MOV DX, 3F0h ; SPIO Index Port
MOV AL, F1h ; Watchdog timer units register (WDT_UNITS)
OUT DX, AL ; Point to register WDT_UNITS
INC DX ; SPIO Data Port
MOV AL, BL ; WDT_UNITS value
OUT DX, AL ; Write the new WDT_UNITS value
; Select the watchdog timer timeout value ...
MOV DX, 3F0h ; SPIO Index Port
MOV AL, F2h ; Watchdog timeout value (WDT_VAL)
OUT DX, AL ; Point to register WDT_ VAL
INC DX ; SPIO Data Port
MOV AX, 37 ; New WDT_ VAL value (from 0 to 255 - seconds in this
case)
OUT DX, AL ; Write the new WDT_ VAL value
; SPIO: exit from configuration mode ...
MOV DX, 3F0h ; SPIO Index Port
MOV AL, 0AAh ; SPIO Configuration Mode Disable Key
OUT DX, AL ; Exit from configuration mode
• Note: for further information about the watchdog programming, refer to “FDC 37B78x
Advance Information”
manual from SMSC.

69
Watchdog time-out pin
For external control purposes, the status of the watchdog time-out event is provided to connector
J11 pin 9. This signal goes high when the watchdog resets the system. The software can reset
this signal by setting and resetting bit 2 of the I/O port 110h. This signal is also initialized by
hardware at power-on.
The following example shows how to reset the watchdog time-out pin:
MOV DX, 110h ; Control Port
IN AL, DX ; Read actual value
OR AL, 04h ; Mask reserved bits and set bit 2
OUT DX, AL ; Write new value
AND AL, FBh ;
OUT DX, AL ; Write new value
Mask reserved bits and reset bit 2

Operating Temperature Range
For proper operation of the CPU module, the ambient air temperature must remain inside this range:
0°C to +60°C (+32°F to +140°F).
74
75
Note. In order to ensure proper operation and good reliability up to +60°C of ambient air
temperature, the Geode GX1 chip and the Geode CS5530 I/O Companion are supplied with an
attached passive heat sink.
Battery Backup Characteristics
There is no configuration data saved by the BIOS into the CMOS Real Time Clock. Therefore, the
module does not need a battery except in the case of applications that need to hold the date and time
at power-off.
Note. Setup data is stored into the BIOS Flash EPROM; it is therefore impossible to lose the
setup data due to a lack of backup-battery supply.
Absolute Maximum Ratings
Table 26. Absolute Maximum Ratings
Supply Voltage: Vcc: 0.00 to 7.00V
Storage Temperature Range: -40°C to +85°C (-40°F to +185°F)
Non-Condensing Relative Humidity: <95% at 40°C (+104°F)
Operating Temperature Range: 0°C to +60°C (+32°F to +140°F)
A SpacePC 1232 CPU module with an extended Operating Temperature Range, –40°C to +85°C, is
also available.
Warning! Stressing the device beyond the “Absolute Maximum Ratings” may cause
permanent damage. These are stress ratings only. Operation beyond the “Operating
