It don't work :D
I can't believe that, whit enabled orginal printfs it don't work. Whit disabled ones it work normally.
Sorry, for this run I have made a mistake.
You can ignore the results. The proper logs was sent to Richard.
With testbios there is also a long delay after the first int10.
The debug spokes out about 5MB of ff for inb, than I have stop the run. After that I have disabled the inb printf and all went fine.
Now I wait for an answer from Richard.
