No GUI Bootscreen Turns Black for 20 Sec. Before Logon Screen

Hey,

I have gotten my Vista boot time down to 1 minute 10 seconds which is fine,
but there is a 20 second period of Black-screenedness after the No-GUI
Bootscreen (MSConfig) says "Starting Windows Vista" that I am wondering
about. To start from the beginning: I select No GUI boot in System Config,
and restart the computer and find that I get the pretty green logo at first,
and then it says "Starting Windows Vista" [fine], and after a total of 30
seconds it is all done [fine].

At that point, my screen (HP laptop NC6400 with 2Gb memory, 1.83Ghz
Core2Duo, Intel 950) goes black for 20 seconds before then going to the logon
screen and finishing up. My guess on the black screen is for doing the
prefetching and superfetching that Vista does, but if that's not what is
going on there, or if I am the only one who gets this, then perhaps there is
a some other sort of problem. My computer works fine and displays no errors
once in Windows and the boot time is not unreasonable, but the black screen
is a bit strange. When you go with the default Boot screen (No No-GUI Boot),
the bootscreen with the bar stays up until the logon screen so there is no
black screen. It still takes the same amount of time with the other screen,
but never goes to black.

This is either normal, or a problem, but I don't know which one!

Thank you very much!

Andrew
