[Cooker] diskdrake problem with win 9.x
Hello Pixel, hello everybody,
the famous german comuter magazine "c't" has an article on multi boot
computers in its new number officially published on monday 2000-07-31.
They have a special paragraph dedicated to Linux Mandrake 7.1 and its
incorrect partition labeling. As I have no M$ 9x or NT on my machine
I can't confirm the content. But I've tried to translate it in english
to let you have a look into it.
