Using Windows 2000 to make bootcreens for bootskin

I made the 16 bit image for my bootscreen and I wrote the configeration data for my ini file. I made a folder to put my image and config data into the same folder. I loaded my screen into bootskin and it works!. I just have a few questions do I have make a progress bar to go along with my skin or can I keep my bootscreen the way it is without the progress bar?. Furthermore, do I have to edit any other system files or could I keep things the way they're?.
