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

The Nokia IP330 is originally a Firewall that runs on the proprietary IPSO operating system of Nokia, it was based in the FreeBSD operating system. 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;

  • Power LED
  • Fault LED
  • 2 Serial interfaces COM1 and COM2
  • 3 Ethernet RJ45 sockets
  • Reset button
  • 1 Compact PCI slot

At the back the following can be found;

  • EURO Power connector
  • Power switch
  • Three FANs for system unit cooling
  • One FAN for CPU cooling

Development status

The current development status is; No coreboot running yet

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 following;

  • For the connectors on the mainboard of the Nokia IP530, due missing documentation of the manufacturer.
  • To create a flash option board on the J-DEBUG connector.
  • To create a USB port.
  • HOWTO read the status of the jumpers.
  • HOWTO enable/disable the LEDs.
  • The layout of the SPI eeprom behind the SuperIO.


The J10 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.

 #define REG_GP1x		0xF6
 #define JP900		        0x20
 sio_enter_config( 0x3F0 );
 val = (sio_read( 0x3F0, REG_GP6x ) & JP901);  
 sio_leave_config( 0x3F0 );

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.

 #define REG_GP6x		0xYY
 #define JP901		        0x80
 sio_enter_config( 0x3F0 );
 val = (sio_read( 0x3F0, REG_GP6x ) & JP901);  
 sio_leave_config( 0x3F0 );

Front LED

LEDs in front
LED Control line Description
Fault FDC37B787-GP13 active low
 #define REG_GP1x		0xF6
 #define LED_FAULT		0x08
 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.

0x7E-0x7F 2 bytes 0xFF,0xFF Unknown, probably the checksum value, but not used therefore filled 0xFFFF

On coreboot startup the eeprom is read, to determine if its a IP530, otherwise it get signaled. And the revision of the hardware. When its reads an unknown (at that time) herdware revision, revision B will be assumed.

Be aware when accessing the data the addresses above are byte address, they need to be converted in word addresses.
