The wiki is being retired!

Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to Contributions welcome!

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:

  • CPU: Socket 7, AMD K6 II at 266 MHz normally,
    • Some later models of the IP330 had a K6 II at 500 or 550 MHz. Special cooling shroud needed on those.
  • I430TX northbridge.
  • 82371 southbridge.
  • intel 21150 PCI to PCI bridge.
  • 28F200, 256 Kbyte flashrom.
  • SMSC FDC37B932QF superio with 1024 bits SPI eeprom attached.
  • LM72 temp controller.
  • 3 intel 82558B ethernet controllers.
  • 2 SD-RAM sockets.
    • 64 Mb SDRAM by default. Definitely takes a 256 Mb PC133 fine, and rumoured to take a maximum of 512 Mb SDRAM.
    • On early models there is one SDRAM slot, and solder pads for a second. Later models have both slots.

Below the description is given for the following;

  • For the connectors on the mainboard of the Nokia IP330, due missing documentation of the manufacturer.
  • To create a flash option board on the J-DEBUG connector.
  • 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.

0x38-0x3D 6 bytes 0x55 Filler
0x3E-0x3F 2 bytes 0xYY,0x00 Mfg. rev. (on the bottom side of the unit), 0xYY = is the revision letter, where A = 0x41, B = 0x42

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.
