Hardware: HM77 Express, GPUIntel HD Graphics 4000, Intel Core i5 3337U (dual-core) (1.8 GHz) Turbo up to 2.7, DDR3 Memory Speed1600 MHz 8GB, 120 GB SSD
I tried to use Bootloader 3.0b and synoboot_3615 .zip!
It seems that the network card is not recognized!
It works withe the 6.1 firmware and the older bootloader
