The patch that supported combined > mode for you is in there. > Just had a quick look at everything that contains "SATA" or ICH in the patch list from RedHat, and there are two : - one concerns pci_quirks and pci_irqs, - one concerns ata_piix.c and libata.c If the first one seems quite OK, the second one implies going back to libata 0.93 and switching to the "old" ata_piix.c, as the one in the 2.4.32 kernel contains : if (combined) { ... return ENODEV; } thus clearly preventing devices from being detected when combined more is there. Do you really think such a big step back is required ? Regards, Paul
