The silence on this question is off putting, I hope you answer it @khile. Wish there more sharing both from Jun and others... like @IG-88 's drivers guide. I can understand not sharing it so its harder for Synology but cmon!@
Yeah that is what I was using, doesn't seem to boot properly though. Using the same settings on a Ubuntu live disc results in a network connection but not with the v1.02a2 img weird. Will start fresh and see how I go.
Turns out the vboxmanage convertdd command did convert it ok, it was the PC i was using it on didn't have VT-x. Now to work out why I am not getting an IP address in bridged mode, which Network card did you select?
