Does your CF/IDE adapter support DMA ?

Is there some way I can figure it out? I'll have a deeper look on the
datasheet when I'm home again later, but I'm rather sure there wasn't
anything mentioning supporting data transfer modes..
Some take care to document this. I checked dma capability
before bying mine. mini-itx.com seems to get this right.

I have returned the adapter card, it indeed didn't support DMA (I checked the pins on the board, pin 21 and 29 are necessary for DMA support and they weren't wired). I bought a new one which explicitly supports DMA and will report when it ships. :)

Best regards,
Philipp
