beyond win 95 ...
means from all versions of windows that supported PnP
win 95 later versions supported it .. but it wasnt as good
thats y we say from win 98 onwards
so this includes win 98,win2k,winme,winxp,win2k3
and linux distros as he mentioned ...
and yeah pradeep was right
that option in the BIOS was for PnP compatible OS's ...
its to be disabled for OS's which do not support PnP
i was unsure of this at first but i looked it up !
