Installed via nanobsd to a compact flash card on an Habey 6620II Z530, but there doesn't seem to be anything wrong other than with boot0sio, or something with how nanobsd installs boot0sio (NOT boot0- that works).  But I have checked what nanobsd is doing, that seems ruled out, seems fine.  BIOS seems ruled out.  Seems like boot0sio.

I get a blinking underscore in the upper left hand corner of my screen (and nothing on the serial port) for a very long minute before the system boots.  Doesn't matter if I have serial attached or not, etc..

I've seen this too. I do not known a reason. And since I do not use physical serial console
I just replace boot0sio with boot0 while building NanoBSD and skip the problem :-)
