I connected the cf to ide adapter to an ide to sata adapter and using this=
=20
combination on sata_nv makes no troubkes whatsoever. So what goues wrong wi=
th=20
pata_amd/amd ide driver? BTW, I found specs for the cf card on the sandisk=
=20
website. Perhaps someone wants to check whether the amd drivers deal=20
corretcly with the true ide mode implemented in the cf card?
