In Photoshop: Image -> Mode -> Grayscale, then File -> Save -> Format BMP, click OK, Windows, 8 bit
In Paint Shop Pro: When making a new image, just specify Greyscale (8 bit) in Image Type. If you didn't do this, do Colors -> Greyscale, which will convert it to 8-bit greyscale automatically. Then do File -> Save, choose Save as Type of Windows or OS/2 Bitmap.
In Paint, just make sure you only use gray colors (RGB values must be the same for each gray). Then save it as a 256 Color Bitmap.
