"This system has relatively little memory. For a system like this, special
procedures are required, because there is not enough RAM available
to run the graphical program without the virtual memory provided by the swap
partition. Thus, you should:

1. Run the disk partitioning program to add a \"Linux swap\" (type 82)
   partition and the \"Linux native\" (type 83) partition. You have to create
   an extra temporary root partition that has at least 1.2MB and type 81
    (\"Linux/MINIX\").
   You will not be able to re-partition the drive while the
   swap partition on it is active.
2. Then initialize the swap partition.
3. Then initialize the temporary root partition
4. Reboot.

Please select an action from the menu below:

1. Run the disk partitioning program in order to create a swap partition."
