If you can read german - there is a "raidpatch" (short) documentation and
zipfile for W2K SP4 and WXP SP2 at http://www.heise.de/ct/ftp/05/03/090/ . The
warning (at http://www.heise.de/ct/05/14/166/default.shtml) is: if a Microsoft
patch affects the patched files then you might loose the functionality again -
and maybe your data, too. So you should make an image of your system partition
before you apply a MS patch.
hope this helps,
