VIP/PID: tool recommended inside here USB view and integrated into XPENOLOGY TOOL V.1.4.0
Setting up a device with DS3615xs in combination with 6.1 on bare metal is a peace of cake for me I only struggle with 6.2 using DS3615xs with 1.03b (starts and works fine but no NIC activity after updating to last 6.2 version, which is fine for other user inside here). Yesterday I have seen the 1.04b loader in combination with DS916+ but there I have the discussed issues.
