Can IDE to CF adpaters (female type - which connect directly to motherboard, without any cable), the 3.5" disk connector type, can they be powered directly from the motherboard? Most of them have a floppy-type power connector on them, but some of them have a jumper which allows them to be powered from the motherboard IDE socket, without connecting the floppy power. But in some description I have read that that only works on VIA EPIA motherboards.
How does the situation really look like? I want to use a CF-IDE female adapter in a standard PGA370 motherboard (non-VIA-EPIA), and I don't want to have to connect any extra power, like the floppy power to it.
Is that possible? I know it's possible for 2.5" disk connectors. because they have 4 extra power pins, but I mean the standard 40-pin IDE connectors.

The regular IDE connector has one unused pin which is sometimes used for keying the connector mechanically. Some embedded systems put 5V on that pin, but I doubt any standard motherboard does that.

Epia-SP's (Mini-ITX) have the extra #20 IDE pin with the 5V. A quick snip with the cutters and it's permanently cured. Or you can look for IDE cables with the full 40 pins.
