This page lists the coreboot status of the Nokia IP530 mainboard. It's maintained by Marc Bertens.

front view

The Nokia IP530 is originally a Firewall that runs on the proprietary IPSO operating system of Nokia, it was based in the FreeBSD operating system. The original is only capable of starting a FreeBSD FS. There is as far as I known no CD support in the orginal BIOS.

The System has no VGA, all console activity must be done through a serial console.

At the front the following can be found;
board view
  • Power LED
  • Alert LED
  • Fault LED
  • Primary IDE activity LED
  • Secondary IDE activity LED
  • Two drive bays (primary IDE and secondary IDE)
  • 2 Serial interfaces COM1 and COM2
  • 4 Ethernet RJ45 sockets
  • 2 PCMCIA slots
  • Reset button
  • 3 Compact PCI slots (industial PCI)

At the back the following can be found;

  • Power supply
    • EURO Power connector
    • Power switch
    • LED 'PWR OK'
    • LED 'FAULT'
    • LED 'OVR TEMP'
    • two FANs for power supply cooling
  • Dual FAN unit
    • two FANs for mainboard cooling

The current development status is; Coreboot runs with seaBIOS. Linux 2.6.32 runs on the system, and most devices are supported. But there are still things to findout. Currently one IP530 runs as a server with Ubuntu 10.10.

System Setup

On board of the IP530 can be found the following:

  • Pentium III.
  • I440BX northbridge.
  • 82371 southbridge.
  • intel 21150 PCI to PCI bridge.
  • 28F400, 512 Kbyte flashrom.
  • SMSC FDC37B787 superio with 1024 bits SPI eeprom attached.
  • LM78 power controller.
  • 4 intel 21143PD ethernet controllers with KS8716 PHY interface, with each a 1024 bits SPI eeprom attached.
  • Texas instruments PCI1225 PCMCIA/Cardbus controller with TPS22061 slot controller.
  • 4 SD-RAM sockets.

Below the description is given for the connectors on the mainboard of the Nokia IP530, due missing documentation of the manufacturer.


The JDEBUG connector can be used for attaching an external ROM (flash chip) to the board for BIOS development.

For recovery there can be placed an flashrom board on the J-DEBUG connector. Belowe here the schematic in PDF can be used.

Schematic ROM option board

As wel the PCB layout in PDF, for this print it on a transparant paper in the highest quality (so it will be very black). From this a PCB can be made.

Printed Circuit Board (PCB) layout

The 34 pin connector shoud be female 90 degres, so that the board is upright when attached to the IP530. you can select a 32 DIL socket, 32 PLCC socket, but not both flashroms inserted only one at the time.

The overview can be used to place the components and solder them in. The red lines in the overview are wires that need to be soldered in.

Components overview PCB

When ready flash the rom in a programmer and inserted it into a socket. Attach the board to the main board of the IP530 (notice the PIN 1 of both boards, when you put it wrong the flashrom on the option board will be blown-up.

Jumper JP800 - BIOSCS select

This jumper selected the on-board flash or the J-DEBUG connector where the BIOSCS# line is routed.

J800 Jumper
Pin# Name Description
1 JDEBUG.P22 This is connected to PIN 22 of the JDEBUG connection on the board
2 BIOSCS# Connected to the ROMCS# line of the Northbridge
3 CS# This is connected to CS# of the on-board flash chip.

The WP# line of the on-board flashchip is controlled by Pin39 of the SMSC FDC37B787 Super I/O chip.

On the production boards the J800 is not present and the R814 (0 Ohm) is placed, remove this resistor and solder in the 3 pin-jumper for JP800. And place the jumper on position 2-3 to select the on-board flash chip.

Jumper JP900

This is a input signal on the Super I/O chip.

J900 Jumper
Pin# Name Description
1 GND Ground of the system
2 GPIO16 Pin 4 of the SMSC FDC37B787 Super I/O chip.

Pin 2 is pulled-up by resistor up VCC.

Jumper JP901

This is a input signal on the Super I/O chip.

J901 Jumper
Pin# Name Description
1 GND Ground of the system
2 GPIO67 Pin 90 of the SMSC FDC37B787 Super I/O chip.

Pin 2 is pulled-up by resistor up VCC.

Jumper JKBD

JKBD Connector
Pin# Name Description
1 VCC VCC +5 volt
2 DATA The DAT line of the PS2 keyboard (pin 70 SMSC FDC37B787)
3 CLOCK The CLK line of the PS2 keyboard (pin 71 SMSC FDC37B787)
4 GND Ground of the system

Front LEDs

LEDs in front
LED Control line Description
Fault FDC37B787-GP13 active low
Alert FDC37B787-GP17 active low
 #define REG_GP1x		0xF6
 #define LED_FAULT		0x08
 #define LED_ALERT		0x80
 sio_enter_config( 0x3F0 );
 val = sio_read( 0x3F0, REG_GP1x );
 // To enable the ALERT led
 val &= ~LED_ALERT;
 // To disable the ALERT led
 val |= LED_ALERT;
 // To enable the FAULT led
 val &= ~LED_FAULT;
 // To disable the FAULT led
 val |= LED_FAULT;
 sio_write( 0x3F0, REG_GP1x, val );
 sio_leave_config( 0x3F0 );

By using the sio_xxx() functions from flashrom, makes easy work dis-/en-abling the LEDs in the front.

The rest of the of the EEPROM is filled with 0x55.

USB Connections

This requires two wires to be soldered on the backside of the mainboard, pictures will be added later

Ckick on the image to see a larger view

Put the mainboard upside down, and the power connector facing you. Find the footprint of the 82371 southbridge. Locate the two pads; i directly above (about 1.5 mm) the F1 pin of the SB, and 1 to left (about 15mm) of the A5 pin of the SB.

Solder two wires to the two pads, be aware that the USB lines are polarity sensitive !!!

 USBPxN >---+---|_____|---+---------> USBPx- to connector pin 2
 * pickup from somewhere on the board the power lines VCC 5 volt and GND (for instance on the JKBD connector pin 1 for VCC and pin 4 for GND)

With this you have succesful added the USB port on the Nokia-IP530. Below are the schematic and board layout in .PDF format for the USB interface.

Installing/booting the Nokia-IP530

The IP530 came with 8, 16 and 32Mb CF cards. There is available for download a 32Mb image that will start with the vendor bios. This image which can be placed on the standard CF card of the IP530.

 #[sudo] dd of=/dev/<cf-card-device> if=./linux-nokia-ip530-coreboot.img

Download 32Mb CF card image (7.9Mb)

This is not a distrubution, but a lean and mean installation with a stable kernel. This image is intended to be used for upgrading, testing and developing coreboot on a x86 system.

Place the CF card in the slot of the IP530, connect a serial cross cable. get a terminal program (like putty) set the speed to 115200 Bps None, 8, 1 and boot up the IP530.

You must get a prompt.

When installing Linux on/for a Nokia-IP530, there are two ways; 1 use a donor PC or installation of a distro that uses the serial console for its installation. The kernel boot customation, must be something like this "apci=off console=ttyS0,115200n8" apci=off is nessary due that the Nokia-IP530 coreboot bios does'nt support APCI yet. Make sure that the ttyS0 is enabled in inittab, or some other place depending on the distro.

Other OSes

It should be posible to run any OS that is able to run without the following devices:

  • Videocard
  • Keyboard
  • Mouse
  • Floppy
  • Paralell port

OSes tested: Linux 2.6.32 and freeBSD 8.1 (unknown if all devices work as they work under Linux)

But NO windows :-)


Depending on the board revision, the board revision can be found on the inside of the machine, its on little stickers on the right-side of the board. There are currently to revisions (A/B) available doe the IP530.


Both rom images are on the Download 32Mb CF card image (7.9Mb)

For flashing the images read the documentation of flashrom.


Havefun with your Nokia-IP530, any remarks about this please email me on pe2mbs@yahoo.co.uk

You can mail me too if you have a board revision that is not supported yet, you must be able to load the rom image "coreboot-nokia-ip530-board-rev-b.rom", but be prepared that maybe not all hardware is working.
