How to keep kernels more than 1

Hi, My suse box failed at 2.6.5-108 kernel at founding and mounting the filesystems. * My machine is DELL PowerEdge 1600 SC (dual Xeon). All partitions are formatted as ext3. When the Yast upgrade is done, Yast deletes previous kernel and keeps latest kernel only. If latest kernel doesn't work, I must reboot with install CD-ROM and overwrite kernel package with default one. First distributed kernel package works fine. I want to keep default kernel and try to use latest kernel package. And also, I will try to make monolithic kernel. Does the Yast have options to keep multi kernel packages for selectable booting ? Regards. Listeny.
