Got a new ACER Aspire ES1-111m and as soon as I took it home I went into the bios settings didabled secure boot, enables F12 boot menu, rigged up a usb dvd with the install DVD and booted.

Boot looks normal but then once I go about saving the original OS I fail to find the internal emmc drive. In /dev/there are no sd? not mmcblk?.
I went back to into the bios setup and enabled legacy boot but I still cannot see the internal emmc drive. In legacy mode though if I put in an SD in the slot it shows up (nothing happens in uefi mode).

I could probably install to a USB stick or a SD leaving the original OS on the internal EMMC untouched but that would be less then optimal.

Anyone know ho do work around this issue ?

Before installing I made bot a raw copy via DD of the internal EMMC and then also made a rescue image from the ACER utility.

I was able to install 14.1 by using current's usb boot image (from premounder 14.1 file tree).
The installation did not leave me a working elilo ... hadto fiddle quite some time to get it working.
Also had fun figuring out how to produce a valid initrd for a luks setup on EMMC.

I hate the way the touchpad works (not sure if it gets 2 buttons on windows depending on which side you push) but in linux it's one physical button. I've worked around setting up key shortcut with ctrl+mouse button clic.
The multifinger tap thing seems to work ... at least after appending i8042.nopnp to kernel parameters
2 finger tap=middle button
3 finger tap=right button
but this only works with the xf86-input-synaptics driver ... not on the text console with gpm.

The BCM43142 will sort of work as long as you get the wl driver from broadcom and you blacklist and remove bmca module prior to loading wl module. On my system it came up as eth1 but I had it renamed wlan0.
The problem is that kernel panics as soon as I start using it to actually send data around in my wifi.
As far as I'm concerned broadcom's driver is far from functional.

I patched broadcom's driver with a patch from archlinux AUR and I had a partial success:
Wifi is now usable but now if I boot the system off battery power it will hard power off right after loading bluetooth modules.
This odd thing does not happen if AC power is on while the system boots and once you get to the login prompt the ac power can be removed.
Having to boot a portable device off mains power is basically killing the portability so I'm not having that !!!

I've worked around this issue by blacklisting the bluetooth modules and now it can boot off battery power and wifi is still usable.
There has been one more positive side effect of blacklisting bluetooth modules: the the touchpad seems to have stopped doing crazy things.

I still got some sporadic hard poweroff during boot so as suggested in this article on ark wiki I also blacklisted dw_dmac and dw_dmac_core but that did not eradicate the problem. I decided do build the kernel again this time removing all I could that was not relevant to my netbook and this seems to have done a better job so far.

I've attached the 4.4.1 kernel config I used.

Today I upgraded to kernel release 4.4.2 (same config as previous) and the touchpad seems to have gotten even more stable.
