can't you make partition1 dasda1 /boot and partition2 dasda2 the PV for LVM?

Hi all, Just a followup question (Mike and I are working together on this): We're considering this layout due to some difficulty we had in the SLES installer. Ideally, we'd like a 3338 cylinder 100 disk with /boot (ext3 filesystem) and the remaining space used for an LVM volume, so 2 partitions total. However, when we create the /boot ext3 partition, the LVM button doesn't allow us to use dasda any longer for a Volume Group. If we take off /boot, we can use dasda, but since /boot can't be on the LVM this won't work either. It's almost like once you put an ext3 filesystem on dasda, you can no longer use it for LVM. Has anyone run into this situation before? If so, is there a way to put 2 partitions (1 ext3, 1 LVM PV) on dasda during install?
