Logo Modding Guide!

I'm sure most of you are aware that
you can change several logos in windows, mainly the splash screen
during bootup, and the System Properties logo. This is a quick
guide for those of you who've wanted to try these customizations,
but are not quite sure how to.
May be worthy to note that these mods will work
only in Windows 95/98/ME, with the exception of the System Properties
mods, which may work in WinNT/2000 also.
Starting in Windows 95, you were able to change
3 screens: the bootup splash screen, "Windows is now shutting
down" and "You may now turn off your computer". These files were
LOGO.SYS, LOGOW.sys and LOGOS.SYS respectively.
You will be able to find LOGO.SYS in C:\ and LOGOW.SYS
and LOGOS.SYS in C:\Windows. They will be hidden, so make sure
you have explorer set to Show all Files. Don't panic if you don't
seem them, though. Starting in Windows 98 these files were built
into windows libraries, and aren't separate files anymore. This
isn't a problem though, because if the separate files exist, Windows
will use those instead of the built-in ones.
So without further adieu, lets make a bootup splash
screen (LOGO.SYS). I'm gonna use Paint Shop Pro 7 for our purposes.
We're looking to create an image that's 320x400 pixels, at 256
I may as well tell you this right now, this is
the first time that I've ever used PSP, so any emails sent to
me about doing stuff in it will fall on deaf ears :). Check out
sweet PSP tutorial site instead. Now, create!
When you've got your screen ready, save the file
as a bitmap, filename is C:\LOGO.SYS.

We'll have to do one more thing so windows will
recognize the logo properly. Right click on the file in explorer
and hit properties. Right at the bottom make sure the 'Hidden'
attribute is checked.
Don't worry about the archive attribute (click
Alright, reboot windows and see if it took! If
so, grab a beer (or your favourite drink) :)
theres a border!
So, you've just started up and the logo looks
great, except theres a border around your image. Well, Windows
creates a border using the first colour in the palette. I don't
think theres a way to turn this off, so if you don't want a border,
just make sure the first colour in your palette is the same colour
as the background of your image (in my case, black).
OK, creating a custom splash screen has been
done a million times. But not many have been able to animate them.
You've probably noticed the "progress" bars that MS sticks on
the bottom of their logo screens. How do they animate? They set
20 out of the 256 colours in the image to "scroll" (called palette
scrolling). This creates the illusion of animation without having
multiple frames of one picture. You'll notice that MS set the
last 20 colours in the palette for this.
