#MOTHERBOARD BIOS SPI PROGRAMMER SERIAL#
MSI use a 9 Pin header marked JSPI1 for reprogramming a soldered SPI Serial Flash EEPROM. Short video on SOIC SPI Serial Flash EEPROM removal and refit Some economy boards do not have the ISP header fitted. 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. Normally the Soldered SPI Serial Flash EEPROM would be accompanied by a 7 pin SPI- ISP programming header. There are a few exceptions, DFI and some other makers are using clam shell sockets for these soic Parts Unlike the PDIP type this type are always soldered to the main board as in the photo to the right. This type are much smaller than the PDIP type and range from 4.2 to 5.4 mm square. Macronix 25L1605DPI-12G PDIP EEPROM Image 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.
#MOTHERBOARD BIOS SPI PROGRAMMER DRIVERS#
The PDIP SPI Serial Flash are usually fitted in a socket and can easily be removed for re programming, this is a must and also remembering to keep your drivers up to date – return to home page for more information. We currently have a few different types of both SOIC and PDIP SPI Flash Parts in stock up to 64Mb, on the EEPROM page. And also the SOIC/SOP 8 pin SPI Serial Flash EEPROM. The image on the right above, clearly shows the Asus P5B In system programming header (ISP or SPI programming header). If the EEPROM cannot be programmed using the above means, the BIOS chip or EEPROM would need to be removed from the board for programming.
In instances where there is no programming header, a SOIC Test clip can sometimes be used in conjunction with a suitable programmer to reprogram the BIOS Chip.
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. We are able to program modern motherboards fitted with an SPI Programming header without removing the EPROM. The soldered type on the right can be reprogrammed using the SPI-ISP Header shown next to the EEPROM in the image. SPI Serial Flash EEPROM have been used for some time now on new mainboards and laptop, in place of the larger PLCC and TSOP EEPROM.
