You might need more than 256MB of memory.
Installation does work with 512MB.
The reason for the large memory requirement during installation is the
install process creates a ram disk for the starter system. The ram disk is
ipl'ed and then you use yast to do the installation/configuration to dasd.
Once you ipl from disk, your memory requirement can be changed to whatever
you need.
