Hm, there is even a web page. Nice to know :)

Yes, it is emulation. It takes ca. 20 s to flash the 256K LinuxBIOS.
Flashing a bigger binary takes proportionally more time. Usually I
change one thing at a time (e.g. only kernel) so the need to flash the
whole 4MB is quite rare.

You are welcome! :) Guys from info at artecgroup.com can give you more
information about that.
