"Does 2.6.27.21 use DMA?"
I will check it today evening.
"Is this system equipped with on-board IDE->CF adapter,
or is it an add-on one?"
It is an additional hardware. The hardwer is connected to mother board (IDE
ifc) and CF-CARD is inserted in a slot on the hardware.
"Does this adapter support DMA at the hardware level
(some adapters don't have DMA lines)?"
Take a look belllow, is it what you need?
