 Here I'm documenting my progress on using my ac100-116 "the right way". Feel free to reach me on [[help#irc]], my nick is PaulFertser.
+**UPDATE 24 Oct 2016**: migrated the system to current upstream U-boot and Linux. Everything seems to be nice and reliable. The limitations section still applies.
+Some notes on update:
+  * Needs the latest (from firmware git) ''rt2870.bin'' for stable wifi
+  * Missing ''nvec_event'' so lid open/close events are not generated
+  * To be able to use ''synaptics'' X.org driver the ''elantech'' protocol needs to be forced for ''psmouse'' kernel driver
+  * ''mpv'' works nicely for unaccelerated video playback, including streaming from Youtube and other popular hostings (''ytdl-format=18'' is usually needed)

   * Suspend-to-disk/hibernation (not anytime soon, no upstream support for ARMs)
-  * Internal mic (pending stuw's and leonro's alsa updates, not functional yet)
+  * tegra_wdt watchdog resets the system but it doesn't boot after that for the reasons unknown
   * Proprietary drivers for X and OMX-accelerated sound/video decoding (never tried, see https://build.pub.meego.com/package/files?package=nvidia-tegra2&project=home%3Acxl000%3Atrimslice%3AMer%3Atesting , http://ppa.launchpad.net/ac100/ppa/ubuntu/pool/restricted/n/nvidia-graphics-drivers-tegra/ , mplayer-omx, gst-omx etc)

 I then used my laptop and an SD card, created a single ext2 partition there and unpacked the preinstalled ubuntu rootfs. Copied the ''uImage'' to root and the created modules to ''/lib/modules''. Erased unneeded boot scripts (including ''network-manager'') from ''/etc/init/''. Created there a file to start ''getty'' on ''ttyS0'', 115200 baud. Placed a suitable ''wpa_supplicant.conf'' somewhere on the card. Removed password from ''/etc/shadow'' to give me root login.
-I boot the u-boot.bin via putusb, then <code>mmc dev 1; ext2load mmc 1 0x408000 uImage; set bootargs "mem=509M@0M console=tty1 console=ttyS0,115200n8 root=/dev/mmcblk1p1"; bootm</code>

 Logged in, set password to 1, start ''wpa_supplicant -Dnl80211 -iwlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf &'', then ''dhclient eth0''. Installed ''openssh-server'' and switched to that (because the serial console sometimes stops to function).
