qnx 6.1 startup sequence


I have updated qnx 6.0C to qnx 6.1 (“Nightly Build”). FD drive’s LED lights
on when I have get Welcome window. What is it? Delayed response of drive on
driver start? Why? Floppy is not mounted by defaul (I hope).
And what about .swapfile? In 6.0 I have seen two lines : swap file created,
swap file added. I don’t know was it work in 6.0, because I did not
recomment appropriated lines in sysinit script. Does swapfile work in 6.1?
And how can I disable it?

Thanks in advance,
