The bad news is that FreeBSD-11 (I didn't try head) can't see the eMMC flash. The worse news is that the WiFi adapter is attached to the SDIO. I've given up and returned it.

I did have a look at [1] http://unisurf.com.au/unisurf-14-Notebook.html and wondered who really made them. INSYDE Corp., I see. Cutely, their ACPI tables are mostly listed as 'INTEL INSYDE' :) and it's called a 'CherryTrail'; all news to me. Looks pretty well locked in to Windows. > For the record, I have both good and bad news: > The good news is that setting hint.uart.1.disabled="1" let it boot. > The bad news is that FreeBSD-11 (I didn't try head) can't see the eMMC > flash.

I wondered what possessed you to buy it, going on specs and 'manual'? and what the '32GB Storage' might denote. Good thing you could return it. For reference, just how cheap are they in AU? > If anyone's interested, I've posted dmesg and similar information from both > FreeBSD-11 and xubuntu 16.04.2 at https://www.rulingia.com/~peter/unisurf/ I noticed: CPUs max speed/power 1.44GHz/2W, min 480MHz/600mW so it's low powered enough. but no Li-ion capacity info and it doesn't support S3 suspend! No thermal zone passive control, still, at 8W for 4 CPUs flat out that might be ok. You'd likely want to force HPET event timer (to get C3 idle state), and get that MMC to show up for it to be any use. cheers, Ian

There is also work in progress on sdio, but that's still focused on the lower level support. ?Once that infrastructure is in place, another round of work will be needed to create the wifi drivers. -- Ian
