now that you sent a pull request for a SeaBIOS update, I tried what
would happen with this one. Sadly, while it does fix my hanging Win 7
boot, DOS still hangs while loading display.sys.

Any ideas where to look, or are you going to have a look yourself? When
I tried to debug it a while ago, I didn't see anything obvious, but then
I didn't invest that much time for it either.

I haven't tried out any of the other cases described below.
