I agree it is quite confusing wording. Probably should remove all reference to PATA in the CONFIG_SCSI_ATA_PIIX Kconfig entry. The comment is referring to the somewhat-hidden fact that if you define ATA_ENABLE_PATA in include/linux/libata.h, then libata will support your Intel PIIX PATA controllers, in addition to the Intel PIIX SATA controllers. However, since ATAPI support isn't yet stable, this is of limited usefulness. Jeff
