[Fedora-livecd-list] booting from non-DMA IDE CF card

[Thorsten von Eicken]

I am trying to boot off a CF card plugged into an IDE adapter and the 
card doesn't support DMA. The problem is that with the new libata stuff, 
the traditional "ide-nodma" kernel option doesn't do anything. How do I 
turn DMA off so it boots properly. As it is, it tries MWDMA2 mode, fails 
a few times, switches to MWDMA1 mode, but never goes down to PIO. 
Apologies if this a FAQ, but couldn't find a solution anywhere.
