Preflashed DFI BIOS Chips-EEPROM
Preflashed BIOS Chips are available for most DFI mainboards. If your board isnt in the list you can E-Mail your Mainboard and EEPROM details to us
DFI BIOS Chip Reference
DFI product support is excellent. The files you need are easily located and downloaded. DFI are one of the few makers that realise that people want to mod and play with their machines and have come up with some interesting products.
They really do seem to understand their customers needs. I have had no issues to date locating the needed files on their support website.
SPI Serial Flash BIOS Chip-programming
We also offer an SPI Header programming service for new DFI motherboards that have a soldered SPI Serial flash EEPROM and an SPI header. We also keep PDIP SPI Serial Flash EEPROM in stock up to 2MB or 16Mb in size (SOIC up to 4MB or 32Mb in size).
DFI BIOS Chip Replacement
DFI BIOS Chip Replacement. Boards marked as having an SPI header can be sent to us for programming, or you can buy a replacement EEPROM .
The buttons below are for a replacement EEPROM. If you need to send in a board with an SPI header for programming please contact us in the first instance, although the cost for reprogramming these boards is the same as a replacement EEPROM.
If you live outside the UK and have a board with an SPI Programming header, the cheapest repair option may be to buy a programmed replacement EEPROM or BIOS chip and fit it yourself.
