You're using Windows 95, I take it? That splash screen is controlled by an option in MSDOS.SYS (not IO.SYS.) IIRC, the options is BOOTLOGO= Since MSDOS.SYS is a plain old text file, you can use any plain old text editor to change it. Use ATTRIB -S -H -R C:\MSDOS.SYS first to make the file changable. raster@highfiber.com

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.) >Charles Dye <raster@highfiber.com> wrote in message >news:377d0a8d.335481@news.nmia.com... >> On Fri, 2 Jul 1999 19:46:14 +0100, "David McGuire" >> <Kenny@celticy2k.freeserve.co.uk> wrote: >> >> >...particularly to delete the start-up screen permanently, if anyone >> >knows... >> >> You're using Windows 95, I take it?

For best results, design at 640x480, then reduce X-axis only by 50% (most paint programs will let you do this easily).

You can have a copy of my notes but they're somewhat intelligible. I don't know of any bit map editor on the PC that supports colour cycling directly. There was one for Atari and Commodore, Deluxe painter?, that did.

Use a hex editor to change the byte at offset 0x32 in the file from 0 to 0xEC. It will then cycle the palette entries from 236-255 around continuously.
