   Concerning this posting, I got a lot of replies, and nearly all of
   them mentioned a problem with the VGA Card (16-Bit DMA Access).
   Many people told me, that 16-Bit DMA Access COULD scramble some data
   read from the disk (i mean: read all bytes as 0xff), which causes
   some problems during installation. The told me to put the VGA-Card
   into an 8-Bit Slot and restart the installation (if my INSTALL Floppy
   is still ok - it was scrambled, but it was only a copy :-). This
   worked. And it worked fine :-). I was told to put the VGA-Card after
   the installation has finished back into an 16-Bit Slot (which I did),
   and all worked fine. (Maybe this problem could find its way into
   the FAQ posting...)

   So let me thank all people who helped me to solve this problem.
   THANK YOU  * V E R Y *  MUCH  :-)

   Ok... that's all, folks.
   Salu...
