My first thought was to look up the specs for the HDD in question...
other things to check is BIOS IDE settings.
you can also manually set the dma mode - though for the life of me I can't
recall how off the top of my head...
Oh. Now I know... atacontrol on FreeBSD... forget I said anything... :-)
still, if it is possible in one versuation of unix it should theoretically
be possible in all ;-) right? *BG*
that reminds me - is there a inverse man page list somewhere?
perhapos this needs a new email... pardon me...
