I believe the FTDI chip on the BeMicro gets all of its startup information from the little microchip EEPROM on the board.

Yes, that can be expected. It's the same with USB Blaster.
It's clear, that FT2232 can be used as a JTAG adapter without additional logic (except for the configuration EEPROM). I wanted to know from someone, who owns the bemicro, if it's done there this way. The first question is about the exact FTDI chip type.
I only have the bemicro manual, and I can't clearly see from the assembly drawing if there's any PLD chip that could be possibly work as additional JTAG glue logic. Perhaps someone can share a high resolution photo of the board to identify the assembled parts.
