http://linux-ata.org/driver-status.html#ich5 : "2. Hardware support Intel ICH "IDE" mode Driver name: ata_piix Summary: No TCQ/NCQ. Looks like a PATA controller, but with a few added, non-standard SATA port controls. Hardware does not support hotplug. "Warmplug" support is possible. Update: ICH6/7/8 include support for addressing the SATA PHY registers. This is not yet supported in Linux, mainly because some BIOS do not fill in the necessary (PCI BAR) resources. Update: Boot-time, probe-time issues continue to persist in some cases, related to the "PCS" register. The ata_piix driver in 2.6.18 and later provides a "force_pcs" module option to help users deal with this (values: 0=default, 1=ignore PCS, 2=honor PCS). Play around with 'force_pcs' if you have device detection problems." I think that's a good description of my problem. Since it's also the controller of my hard disk, it's not compiled as a module. How can I use this module option, then?
