On an unofficial Windows XP Pro SP3 Cyber Lite ISO, in the i386 directory, I found two files named BDBD, one in a BMP format and the other one in an INF format. These files display a temporary image before the GUI stage of installation begins (referring to billborards that show after a solid color or temporary background). Can someone tell me more about the aformentioned file and tell me how do I use my own BDBD file for my custom version of Windows?
