Dear All, I had an NSLU2 with firmware version v2.3R24. I downloaded firmware version v2.3R76, no change log and I have updated my NSLU2 successfully thanks to the information obtained on your excellent website. I also noticed that your website threads refer to another file for a UI. NSLU2_UI-ENR02.bin. I have downloaded this UI. Q: What is this UI and how can I tell which UI I am running at the moment? Q: I have already updated my firmware from R24 to R76, I have not updated the UI, do I still need to install the UI R02? Q: If I do need to install the R02 UI is it compatible with firmware R76? Q: If I do need to install the R02 UI please can I have detailed instructions? Many thanks for your support. regards, Haroon.
