Hi
Just to let you know i updated my HP N54L via the online update, DSM 6 is working fine.....BUT....... I had to do a full install losing my config....AND the disk drive will not create a volume on it!!!! so don't do it if you want to keep your system.
Fortunatly this is only a backup of my official box so i just need to roll back the usb key and get it back!!!
Was worth a try.
