Most of the patches necessary to get the IDE controller in the ICH4 (82801DB) on the Intel D845GBV motherboard are already in 2.4.19-rc1. (These are the issues in the mail thread "Anthony Spinillo" <[email protected]> started on June 1, 2002.)
However, the patch to pci-pc.c that JeffN sent him is still needed, as the BIOS on the board (both patches P02 and P04) doesn't allocate any I/O space for the first four BAR's in the IDE device.
So this is confirmation that such a patch is needed, and that JeffN's patch works. I suspect it's generic to all Intel BIOSes that are setting up the ICH4.
I've attached a fresh version of the patch based on the 2.4.19-rc1 baseline.

I also want to add that IDE/DMA has been working great
with 2.4.19pre10-ac2 since the day Alan
put out -ac2
RC1 failed on the DMA for me also.
USB 2.0, and the Intel onboard ethernet have been
working well.
Thanks for all your help,
Tony
