Brett,
Right click My Computer>Properties>Advanced>Startup and Recovery>Edit;
Edit BOOT.INI and delete "/SOS" right after "/fastdetect."
The line will look something like this:
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP
Professional" /fastdetect(when you're finished).
The first part, multi(0)..... may not be the same on your machine. Upon
restarting, the splash screen will be enabled. It can be disabled by adding
the switch.
You can also use MSconfig to accomplish the same result;
Start>Run>msconfig (typed in the caption box)>Boot.Ini (tab) and perform the
same edit as noted above.
