Look at the user documentation, for example: http://svn.oscar.openclustergroup.org/trac/oscar/wiki/InstallGuidePreparing#DistributionRepositories You must have the i386 distro (rpms) in /tftpboot/distro/... and the i386 oscar RPMs in /tftpboot/oscar/... . Then the image build step will offer you a choice on which kind of image you should build (the GUI has a drop down menu). The problem you will currently have is with booting the nodes to install them. I usually copy from /usr/share/systemimager/$ARCH/boot/standard/ the initrd and kernel to /tftpboot/initrd-$ARCH and /tftpboot/kernel-$ARCH and customize two install pxelinux.cfg files (copies /tftpboot/pxelinux.cfg/default), one for each architecture. netbootmgr can help with this, but isn't yet automatic (due to lack of time on my side).
