I have win xp installed and my hardware is pretty new (including sound card). i also have win98se installed on a seperate partition. i used the bootdisk supplied by the site, but it didnt initialise my sound card unfortunately

does anyone know how to make a bootdisk which will work for my specific machine so it boots to DOS?
My soundcard is a Realtek AC97 Audio. My cdrom is a PIONEER DVD-ROM.
i looked everywhere but i simply can't find a clear cut answer. thanks for your help guys
