Here's how you can find out:
- Right click My Computer, Properties, Advanced, Startup and Recovery, Edit.
- Edit BOOT.INI. Add "/SOS" right after "/fastdetect" with a space between. The line will look something like this: multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /SOS.
When you're finished. The first part, multi(0)..... may not be the same on your machine. Upon restarting, the splash screen will be gone. If you have done with this you can be re-enabled by removing the new switch.
