Hi,
I am trying to port our software system (uses a 2.4.20 kernel) to a
new platform which has a ICH6R controller. Due to some reasons we
cannot update our kernel to a more recent one (probably 2.4.27) which
has libata support in it. I can successfully patch the kernel (after
some modifications) with the 2.4.26-libata patch and get the system
up and running using the drivers/ide code. But I cannot seem to get
the ata_piix (scsi layer) working (does not patch cleanly). Is there
a patch available for 2.4.20 that can get the ICH6R support. Or is
there a way to get the dma mode enabled with the drivers/ide code?
Turn off combined mode, and PATA DMA will start working.

Hi Jeff,
Thanks for the reply.
I tried turning off the combined mode but in vain. I still cannot get
DMA enabled. Let me just tell you a little bit where I am. I am using
the native ide support to get the system up (by adding the necessary pci
ids + modification from the libata patch to the piix.c). I cannot use
the ata_piix implementation as I have not found a clean patch for a
2.4.20 kernel. Any ideas?
Any suggestions are welcome.
Sid
