New version of flashrom available. This app can program flash and bios chips using the Bus Pirate:
Latest flashrom binary for Windows (32bit)
This version also has support for plain ft2232-based flashers and thus it needs libusb and libftdi on your Windows machine.

Does it burn predefined ROM data?
Or we can use it for burning ROM data to any SPI or TWI EEPROMs with BusPirate?
Seriously it requires ftdi. I’ve found out my USBtoUART chip was Prolific one (pl2303 maybe) and it didnt worked just gave notice of missing files.
