Does it use DMA ?
No. But it's faster without DMA.
- Looks like it has one RJ-45 and two USB jacks... but are the USB jacks inactive until after purchase of (quote) "local expansion port for forthcoming high-speed USB module"?
Something like that. The USB is currently non-functional and you will have to pay to enable it (2x external USB).
That's all I've read. There may be a few more details here:
