Good question. CF 1.4 says set features supports 01/0A/55/66/81/8A/9A/BB/CC (with 69/96/97 NOP or not recommended) However it documents both the PIO mode and DMA word in identify. I've never seen a CF 1.x card which does DMA or PIO > 2. CF 1.x is sort of ATA-2 ish but without some set features (eg its got idle immediate) and with some stuff that became general later (security features) Alan - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
