Hi Carl-Daniel,
I've taken the board out (wasn't actually hard at all - it is not glued) And here is what I found: * Via VT1612A * Via VT1211 * Via VT6103 * ram chips: HY5DU121622CTP * SST39SF020A which is soldered onto the board :(
Someone with superhuman soldering skills might be able to fit a socket in its place... ain't me. (board is dual layered, so you would have to re-use those tiny pins...) If anyone can, I'll give them a unit for free - just email me.
Cheers Antoine

Hi Antoine,
I'll defer most of your questions to the real VIA experts on this list.

To have any reasonable chance of checking whether coreboot supports your chipset, we need to know exactly which chipset it is (that includes the exact sub-revision). Without that, you'll have virtually zero chance of getting the machine to reach early init at all, and even less so if you want it to boot a payload.

Sorry, without exact chip revisions, there is no reasonable chance to make it boot.
So does it look like it might work from those specs? A lot of the via boards seem to be very similar, does the hardware and payload vary so much that this would be pointless?
To give you a perspective on the difficulty of bringing up a board: Even if chipset and processor are perfectly identical to another board, you will have to go through a few iterations until it works (IRQ routing, GPIO configuration and a few other things usually differ). For your board, we don't even know the exact chipset, so the only way I see is to open the box and write down the numbers on the chips. And please find out whether flash is soldered (will need to be changed) or socketed (good).
