Customizing XP Boot Screen

Ever wonder what's going on behind the boot screen? to find that out, right-click on
My Computer -> Properties -> Advanced -> Startup and Recovery -> Edit. wait until the BOOT.INI is opened in a notepad. Add "/SOS" right after "/fastdetect" with a space in between and save it. The line will look something like this:

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /SOS

Note: the value in between the Open and close braces (0) will not be the same on all computers.
