Hi,
No need to look. The K7S5A is supported. I successfully flashed 5 K7S5A without a hitch. Carl-Daniel marked it as supported already.
Oops, I just realized I didn't look closely enough. spirals was talking about a "K7S6A", not "5A". I guess that board is slightly different. Sorry for the fuss, it's already a bit too late tonight.
