@Jnus,
I've tried to install xpenology in vmware 5.1 on HP N36. Difficult to get de synoboot working. When it boot it stops when grub loader appears. I've converted de synoboot.vdi with winimage to an vmware disk .vmdk. I will try another one (which is known to be good in converting vdi to vmdk).
Will try further this week with xpenology in vmware 5.1
Which setting do you use in setting up the vm in 5.X
