    Большое спасибо! Это решение намного лучше заводской версии прошивки! Было неплохо добавить возможность изменять тему.

    Gave new life to my DNS-325-A2. The stock firmware from D-Link was not that bad but some add-ons were poor, for example aMule add-on. With Alt-F everything works out-of-the-box, my files were preserved and there are a number of add-ons that look interesting. I installed the aMule add-on and it appears to work well, coupled with its corresponding front-end "aMuleGui". The ability to define some shortcuts is really useful for saving time for starting/stopping some services when needed. Keep up the excellent work. Thank you Aldo

    Thank you so much for this... allowed me to expand use of my DNS321 to larger drive sizes and has given it the ability to do self-backups. I just wish I could get the miniDLNA to work...

    Can't figure out this thing at all. About as user-friendly as a sharpened stick. Can't even tell what its doing half the time or if it even properly supports my 4tb Seagates Vague error messages, endless demands to log in whenever I do anything...just a really rough bit of software. Using DNS-321 which from what I can see not that many people have..I can't even find any detailed reports from other owners. You'd need to be a Linux guru to get anywhere with this firmware, I think.

    Hi I boughted NAS D-link DNS 320L, with one WD 3TB hdd, which I placed to slot 2. I have trouble with Alt-F-0.1RC4.1-DNS-320L-rev-A1A2A3 (1).bin. I connected to NAS and upgraded firmware. Then restart and then start my trouble. All diods ( for USB, DISK1 and DISK2 ) glows red, and active slots ( in my case USB and DISK 2 ) glows blue at the same time. When I tried login to DNS,via administrator,nothing happend, my browser after some time writes that the page is unavailable. Can you help me solve this problem, at least return to the original state. Thank you very much for your help.
