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...
