I can also attach a hard disk which Rescatux can see. I believe it is possible to PXE boot this device but you need a specific chipset in your LAN hub. But what is so special about Rescatux. Could I use its EFI with a different OS, afterall it is based on Debian, but Debian itself won't boot
 
No, mmcblk0 is the 32GB (29.1G) of eMMC storage on the Compute Stick. SDA is the 8GB (7.4G)USB stick I've booted from.
That was exactly what I meant. The memory card is what it's built in the compute stick. Can it be removed? Is it like the normal SD-cards we use for phones and cameras? If so, it's quite easy to stick the card in any notebook or card reader and then you can play with it as much as you want. A total restore is possible - just take the complete image of the card on another machine.

If the card is not removable, probably don't bother playing with other OS-es, unless you're OK with bricking the device.
I'm just a little concerned that I won't be able to restore using DD.

I have no idea what these two partitions are, but I guess DD would handle them correctly

mmcblk0boot0 179:256 0 4M 1 disk.
mmcblk0boot1 179:512 0 4M 1 disk.
I would not dd the partitions themselves - it's quite error prone. Simply dd the whole device, so you're definitely on the safe side.
 
You do see your problem right?
Writing a 32GB image file to your 8GB sda0 that you booted from?
dd writes every sector even if empty.

You can always pipe it through gzip, so if the device is mostly empty, it'll just compress it to whatever is the real data size or close.
 
If I manage to copy the image to another location, I'm wondering whether DDing the ISO image of Rescatux to eMMC storage would create a bootable Compute Stick...
 
It seems that my Intel Compute Stick is not a genuine compute stick so I won't get any help on Intel's forums... So I'm wondering if a BIOS upgrade may enable more EFI partitions to boot. Currently I've only found that that Rescatux is able to boot.

Given that I have an American Megatrends BIOS should I expect to find an upgraded BIOS here .

This actually is related to FreeBSD because I want to install FreeBSD on this stick.
 
A BIOS upgrade is always worth it if you have trouble, IMHO. However, I only use the vendor's site to get BIOS updates. Normally each vendor modifies the BIOS for each motherboard, so a BIOS from AMI probably won't help. At best it will refuse to install, at worst it will brick your machine.

What brand and model is your compute stick?
 
Most BIOS / UEFI has one screen which shows the version of the BIOS. And often they show a "model" number for the bios as well, you can use that in google to see if you can find a place to download a bios upgrade.
 
Under BIOS which is described as Aptio Setup Utility, Main shows BIOS Information:-

Code:
BIOS Vendor         American Megatrends
Core Version        5.008
Compliancy          UEFI 2.3; PI 1.2
Project Version     1ASEB 2.41
Build Date and Time 05/16/2015 09:06:04

CPU Configuration
Microcode Patch     82f

https://ami.com/en/products/bios-uefi-firmware/ list Aptio V and Aptio 4

It isn't obvious to me which (if either) I should use... I'll try Apto V and see what happens,

I also notice under

Chipset -> South Bridge -> USB Configuration

this mentions options for :-
USB OTG SUPPORT
USB VBUS
XHCI Controller
XHCI Mode

USB2 Link Power Management

Unfortunately I have no idea what I need to set - maybe it has some impact on external devices - I don't know...
 
You should only update your BIOS when you are absolutely sure it's the right one for your motherboard... If you're not ABSOLUTELY POSITIVE you have the right file, DON"T update!!! Do some more research until you are positive...
