freebsd stable - Apr 2008 - Disable DMA without loader.conf or sysctl.conf.

Hey guys;

I'm back to using FreeBSD, after my major hardware upgrade seriously
broke everything (teach me to optimise...)

I've stuck it on my xbox for now, and it runs like a charm, of course,
except it complains then dies on boot about the HDD having problems
with DMA. It's only using a 40-conductor cable, and 80 works fine, but
the cable is a special length; I need to use the provided one to shut
the case!

Is there _any_ way to disable ata DMA at kernel compile time?
Remembering that Cromwell won't support loader....

Thanks a lot

Chris

That is not correct - recent versions of the sysutils/cromwell port
support passing kernel environment parameters. As for your
/boot/xboxlinux.cfg, use:

title FreeBSD/xbox
kernel /boot/GENERIC/kernel
append hw.ata.ata_dma=0

And it should work. I think I forgot to release ISO images featuring
this :-(
