Thanks Dan, for the quick reply. I have only a IDE disk. # egrep '(CONFIG_IDE|CONFIG_BLK_DEV_IDE)' .config CONFIG_IDE=y CONFIG_BLK_DEV_IDE=y # CONFIG_BLK_DEV_IDE_SATA is not set CONFIG_BLK_DEV_IDEDISK=y # CONFIG_IDEDISK_MULTI_MODE is not set CONFIG_BLK_DEV_IDECD=m CONFIG_BLK_DEV_IDECD_VERBOSE_ERRORS=y CONFIG_BLK_DEV_IDETAPE=m CONFIG_BLK_DEV_IDEFLOPPY=m # CONFIG_BLK_DEV_IDESCSI is not set CONFIG_BLK_DEV_IDEACPI=y # CONFIG_IDE_TASK_IOCTL is not set CONFIG_IDE_PROC_FS=y # CONFIG_IDE_GENERIC is not set CONFIG_BLK_DEV_IDEPNP=y CONFIG_BLK_DEV_IDEDMA_SFF=y CONFIG_BLK_DEV_IDEPCI=y # CONFIG_IDEPCI_PCIBUS_ORDER is not set CONFIG_BLK_DEV_IDEDMA_PCI=y CONFIG_BLK_DEV_IDEDMA=y I am not sure what you mean with CONFIG_IDE_$controller=y The other 3 options are set.
