Socketed SPI Serial Flash EEPROM
SPI Serial Flash EEPROM have been used now for some time on new mainboard's and laptops. However these are the first examples of mainboard's that have socket SOIC SPI Serial Flash EEPROM. Some mainboard makers are fitting SPI Serial Flash EEPROM Clamshell sockets to their mainboard's. This makes changing the EEPROM a lot easier.
So far I have only seen these sockets fitted to DFI and EVGA mainboard's.
One example is the EVGA X58 SLIYou can see the black socket just above the CMOS battery on the X58 SLI. Changing the BIOS chip on these boards is relatively easy. Just be careful to align the number 1 pin correctly when fitting the EEPROM. SPI Serial Flash SOIC EEPROM usually has a small Circular indent near the number 1 pin, and also a half moon cut out at the number 1 pin end. Care must be taken when refitting them, as it is possible to insert them the wrong way around causing damage to the EEPROM |

DFI X58 |

DFI X58 has a clamshell socket for the SPI serial flash EEPROM. The EEPROM can easily be removed for replacement on these boards Other DFI Models that use the SPI serial flash EPROM may well have the socket fitted also. The image below shows the open clamshell SPI Flash Socket fitted to the Lanparty DK X58. The second image is the same socket with the eeprom removed |
