As far as I know my cables are UDMA100 capable but I may have to try changing them next. (soon I'll have more money in drive cables than I do in drives :-( )
I don't remember right now, but I think they are detected by the bios during the boot, or reported somewhere. At least, you can not use the high udma modes if the cable is not capable. Ah, yes, the boot.msg has it:

Swapped my cdrw and dvd from their original positions, now I have: On the first IDE cable: 80gb IDE hard drive (udma100 capable) - linked to /dev/hda 80gb IDE hard drive (udma100 capable) - linked to /dev/hdb On the second IDE cable: ATAPI DVD-ROM - linked to /dev/hdc ATAPI CDRW - linked to /dev/sr1

Ralph also has VP_IDE, and he has problems as well. Mine is "ICH2"

He has the same problem here than you. One question: do you see any thing about ACPI in the boot.msg log? ACPI (Advanced Configuration and Power Interface) is also related to IRQ handling on the new boards, and is also related to APIC. Many people complained of computer freeze problems (including me) and one of the proposals was to disable ACPI; but that may affect how the IRQs are detected and/or handled. In my case, ACPI is enabled, but not APIC (not fully) - if I do, I loose USB. And, DMA and IRQ are related.
(In a message from Carlos Robinson showing part of his boot.log DMA seemed to be set up at this point (snip follows) (<4>ICH2: not 100%% native mode: will probe irqs later <4> ide0: BM-DMA ... , BIOS settings: hda:DMA, hdb:DMA <4> ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:DMA, hdd:DMA)
Yes, but not quite: that only report the bios settings. I have to enable DMA using hdparm later for the dvd, is not enabled when I need it. In yast, I can configure dma for the hard disks, but not for the ide-scsi drives, they don't appear.
Setting up IDE DMA mode
Force IDE DMA mode on: hda hdb done
That's during boot, or later?
So The drives are accessible but DMA mode (doesnt really seem to get set)
What happens if you issue "hdparm -d1 /dev/hdc /dev/hdd"? In your first message you said it failed, but as you have changed the connections, maybe it varies :-? If the command fails, check what it says for hdb and hda as well, for comparison.
Just a comment which may be irrelevant because I have not been following this thread closely. Are the HDs sitting in cradles? I had a hell of a time trying to figure out why I was having big problems with my new HD until I realised that while I had the correct 80-wire cable connecting the motherboard to the cradle body the cable INSIDE the cradle in which the HD is located had the old 40-wire cable :-(. I replaced the old cradle with a new one and the problem disappeared. Cheers. -- Sound that shatters silence is called noise. Sound that enhances silence is called music.
