This is not a hardware problem, this is Flash cards limitation- most of fla=
sh=20
cards don't work with DMA at all.

You should turn off DMA on every Flash card that is connected directly to I=
DE=20
channel to boot up any operating system. I know there is some IDE2Flash=20
adapters that can work with DMA but they are twice or even more expensive=20
than el cheapo adapters most devices got.
