Re: CompactFlash and HD unhappy together on the same IDE channel

[Matt Sealey <matt@genesi-usa.com>]

Having the dual-slot CF-IDE adapter AND a hard disk means you have 3 devices
there whether you plug something into the slot or not.

You'd get the same error if you had a 3-way IDE cable :)

Just move the CF adapter to a different cable, or the hard disk to a different
cable, and it'll be fine.
