Also, the bus mastering drivers need to be loaded for the controller,
which it is in your case.  What can make the system slow is also the
loading of real mode drivers in autoexec/config files.  This makes it
very slow.  You can also check the DMA option in the harddrive tap of
device mananger.  It should be under setting, you can also do that for
the cd-rom in some cases.  I have had problems with some older
machines running with the DMA checked, but you should be able to go
into safe mode and uncheck it.
