This is a repost of an archive I posted in 2015.   This method works for DSM 6.2 using Jun's loader 1.03b for me.     1) Enable SSH and ssh into your DiskStation 2) Become root ( sudo -i ) 3) Make a mount point ( mkdir -p /tmp/mountMe ) 4) cd into /dev ( cd /dev ) 5) mount synoboot1 to your mount point ( mount -t vfat synoboot1 /tmp/mountMe ) 6) Profit! admin@DiskStation:~# sudo -i root@DiskStation:~# mkdir -p /tmp/mountMe root@DiskStation:~
