At the moment it is not, but it may be a neccessary side effect of full support for the later SATA capable controllers in native SATA mode. In which case you might get it one day. The legacy mode is itself as good as most typical PATA controllers and better than some. > > And as last thing I want to ask you whenever current support is usable, > that is can I use DMA , can I use DVD as at least reader for CD/DVD , > and even better can I burn disks with it ( although I can live without it) The legacy mode has full DMA support. What you don't get is the ability to queue multiple commands so the hardware can fire off a new command as the first completes and to have the hardware do some of the general poking around for us.
