hi, on centos 5.x and fedora 6 there are hdX and sdX while from fedora 7 (and probably centos 6.x) there will be only sdX. is it possible with the latest centos kernel to use the same ata_piix driver to handle all disk (ie. both pata and sata) so we've only sdX disk devices like it's the current setup on newer fedora release. we try to disable ide0=noprobe etc. which really disable hdX but even if the kernel load the ata_piix driver it's still not load these disks. thanks in advance. -- Levente "Si vis pacem para bellum!"
