Installing slink with boot-floppies 2.1.8 on a laptop Compaq Armada 1570. When choosing "Partition a hard disk": Invalid partition table cfdisk has failed while trying to repartition your disk... But cfdisk, from the shell, works fine and partitions without any trouble. Note: all the Compaqs have a custom partition, /deb/hda3, for hardware setup and diagnostic tools.
