The ata_piix module doesn't detect that my laptop's disk controller
(Intel Corporation 82801GBM/GHM - ICH7 Family) is configured to have
PATA drives in the first two channels. I looked at Intel's
documentation and they say that my controller isn't supposed to support
this configuration, but it's the default setup on this laptop, there's
no way to change it in the BIOS, and it works in Windows, so I'm
assuming this is a documentation error.
This patch changes one line in ata_piix.c so that it sees this
configuration as valid (and therefore recognizes my drives). I've
tested it on my laptop and the module is now working perfectly (whereas
the kernel was using the old IDE driver previously with no DMA enabled).
I'm cc'ing fedora-devel-list because I'm not even sure where this patch
is supposed to go and I would like it to make it into FC6, as I really
don't want to have to jump through hoop after hoop just to get FC6
installed on my hard drive.
Thanks,
Jonathan
