Look at build 2015 in the middle of the night, basically heard 3, 4 times "Raspberry Pi", but always did not demonstrate win10 in the RPI above what kind of, so ... Try it yourself. First the pit is DISM: see an Ffu file, read the instructions, that is DISM directly deployed to the SD card. So is it possible to use LINUX+DD? Try it, no ... Then using win8.1 for DISM, found error 87, go back to look at the

Setting up Wi-Fi with the Command lineSIMON MONKThis tutorial works best if your router is broadcasting the SSID. Make sure the "broadcast SSID" set up on your router! This could not work with "private" SSID setupsSetting up WiFi in occidentalis, is also pretty straight forward. You just need to add the name of your wireless network (its SSID) and your password to a configuration file.Step 1.Boot the Raspberry Pi

Raspberry Pi has two audio output modes: hdmi and headphone interfaces. You can switch between the two modes at any time. If your HDMI monitor has a built-in speaker, the audio can be played through the HDMI interface. You can also switch to the headset interface to use the speaker of the headset or other headset interface to play the video. If your monitor requests support from the speaker, the sound is ou
