INTEL 845G IDE PATCH for 2.4.19-pre10-ac1

["Anthony Spinillo" <tspinillo@linuxmail.org>]

[-- Attachment #1: Type: text/plain, Size: 444 bytes --]

I assembled 3 diffs based on a patch Andre Hedrick
sent me the other day to enable DMA on the 845G chipset. Hopefully they can help someone else out.
The diffs patch ide-pci.c, piix.c and 
pci-ids.h.

The diffs are on top of linux-2.4.19-pre10-ac1 
(Thanks Alan).

I'm out of PIO hell, but if someone can give them a quick sanity check, that would be great.

Thanks,

Tony
