The problem is that you need the block devices and controller built in as well as the file system. So, SCSI + libata (to use /dev/sd* nodes) or IDE (to use /dev/hd* nodes). For SCSI + libata: CONFIG_BLK_DEV_SD=y CONFIG_BLK_DEV_SG=y CONFIG_ATA=y CONFIG_[SP]ATA_$controller=y For IDE: CONFIG_IDE=y CONFIG_IDE_$controller=y CONFIG_BLK_DEV_IDE=y CONFIG_BLK_DEV_IDEDISK=y -- Dan -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
