I got installed 5.2 with HP Smart Array P410 without problem. And now i try to upgrade to 6.1.3 and make use bootloader 1.02b. I can search it at Synology Assistant but it shows that i have no HDD as below.   I think there is controller driver missing at the bootloader, may i know where and how to insert it into bootloader?   Besides, i using the console HP N54L, any drivers i need to insert, besides controller driver?   Thanks
