what do I need to do to get OES (sp2) to boot after installation when
installing on software raided disks?

My system is Sun X2100 /w 2 SATA disks (nvidia sata). OES doesn't recognize
the builtin sata raid, so I skip that and use software raid. I create 3
partitions,: /boot (md0), swap (md1) and / (md2), all of them s/w raided.

Installation goes fine, no complains but the machine is not able to boot
anymore. Grub seems to be completely broken after installation when viewed
afterwards in rescue mode, lilo is not broken but doesn't work either.

Is bootable software raid really impossible with OES?
