Why don't you take my OVA with 918+ (6 posts up)? That works without doing anything on Haswell i3-4130. Deploy OVA, add existing disks/controller, find with Synology Assistent and click migrate, which will take you straight to 6.2.1 update 4. As a bonus you'll get VMXNET3 and PVSCSI (when using virtual disks) which will give you better performance. It already has MAC/SN set correctly, bootloader disk moved outside of the visible range, etc, there is nothing left todo, besides installing VMware Tools (link included in that post) and maybe updating apps.
