F12 text mode and disk layout

[Andrea]

Hi,

I've just installed F12 on a PS3.
Only text mode installation works due to the amount of RAM available.

I would like to partition my hard disk to have / and /home in a different partition.
Single big reason is that new reinstall I keep /home instead of loosing it.

So,

the closest I got to partitioning was a menu with 3 choices

- use entire disk
- replace linux system
- use free space

none of them took me to a partitioning tool.
I can see in the installation notes a picture of such a tool

It is Figure 6.2 in this page

How do I get there?
