SPI-ISP Programming

We are able to program modern motherboards fitted with an SPI Programming header. Cost if you have an SPI or JSPI1 programming header fitted on your board is 12.49 plus return postage at cost.
Providing you have the required SPI header connector on your mainboard then it should be possible to replace the data in the SPI Serial flash EEPROM without lifting the EEPROM.

Most PC mainboard's that use the SOIC SPI serial flash chips do have the required SPI header needed for programming the SPI Flash Device, but not all.

If your Main board does not have an SPI-ISP programming header then the BIOS Chip may need to be removed from the board for programming at a cost of £19.99 plus return postage at cost.

SPI Serial Flash EEPROM

We currently have a few different types of both SOIC and PDIP SPI Flash Parts, on the EEPROM page. The image on the right clearly shows the Asus P5K-VM In system programming header (ISP or SPI programming header). And also the SOIC/SOP 8 pin SPI Serial Flash EEPROM.

PDIP SPI Serial Flash EEPROM

The PDIP SPI Serial Flash are usually fitted in a socket and can easily be removed for re programming. See the image on the right. Care must be taken to make a note of the orientation of the device as it is possible to refit them incorrectly resulting in damage to the EEPROM.

SOIC SPI Serial Flash EEPROM

This type are much smaller than the PDIP type and range from 4.2 to 5.4 mm square. Unlike the PDIP type this type are always soldered to the main board as in the photo to the right.

Normally the Soldered SPI Serial Flash EEPROM would be accompanied by a 7 pin SPI- ISP programming header. In most cases the SPI-ISP programming header is marked SPI and can be used to re program the EEPROM in place on the mainboard. Some economy boards do not have the ISP header fitted.

SOIC SPI Serial Flash Ziff Sockets

SOIC SPI Serial Flash Ziff SMD sockets are available form the home page

MSI JSPI1 Header

MSI use a 9 Pin header marked JSPI1 for reprogramming a soldered SPI Serial Flash EEPROM. Unlike other makers who seem to be using a 7 pin header marked SPI

If you need to send in your board, handle your board carefully to avoid Static damage, and make sure you use a good strong box, and NOT A JIFFY BAG and an anti static bag if possible.

Spi Header Pinouts

Common SPI Programming header pinouits for  Most mainboards with a 7 pin header, although it may not apply to all makers may choose to design their own headers. Some have been using them for many years
