IO.SYS is the DOS kernel.  It's mostly machine language.  You don't
really want to mess with it, unless you're skilled in 80386 assembly
code.  Yes, it does contain the default splash screen, but I don't
think that it's in any standard graphics file format.

If you want a different splash screen, it's possible to do that by
creating a bitmap, renaming it to LOGO.SYS, and storing it in the
root directory.  It has to have a certain specific resolution -- I
*think* 320-by-480, 16 colors, but could be mistaken.  Ask in a
Windows 95 group; this is probably a FAQ.  Or, if you already
have a LOGO.SYS, make a copy with a .BMP extension, open it
with Paintbrush, and look at "image attributes."

If you want to disable the splash screen, the option is LOGO=0
(not BOOTLOGO, as I erroneously guessed earlier.)
