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:
<6>hda: 117231408 sectors (60022 MB) w/2048KiB Cache, CHS=7297/255/63, UDMA(100)
The corresponding part of my bootlog follows... <6>hda: 156301488 sectors (80026 MB) w/2048KiB Cache, CHS=9729/255/63 <4>hdb: safely enabled flush <6>hdb: 156301488 sectors (80026 MB) w/2048KiB Cache, CHS=9729/255/63 So it appears that in your case UDMA(100) is available while my boot.msg indicates it is not available on my machine (possibly due to cables?) Is this a correct interpretation?

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.
There are numerous references to ACPI and APIC I 'll have to try changing my bios settings, who knows, maybe it will help... ----------snip------------
Setting up IDE DMA mode
Force IDE DMA mode on: hda hdb done
That's during boot, or later?
Its about half way down my boot.msg, A slightly longer snip follows... Boot logging started on /dev/tty1(/dev/console) at Sun Jan 5 13:17:21 2003 Setting up IDE DMA mode Force IDE DMA mode on: hda hdb hdc done Configuring serial ports... ttyS0 at 0x03f8 (irq = 4) is a 16550A ttyS1 at 0x02f8 (irq = 3) is a 16550A Configured serial ports
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.
Still appears to fail. I added "append = "hdc=ide-cd hdd=ide-scsi"" to my lilo.conf Here are the messages returned By my current setup: luna:/home/dh1 # hdparm -d1 /dev/hda /dev/hdb /dev/hdc /dev/hdd /dev/hda: (80gb ide harddrive) setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) /dev/hdb: (80gb ide harddrive) setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) /dev/hdc: (ATAPI dvd/cd player) setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) /dev/hdd: (ATAPI CD-RW w ide-scsi emulation) setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) luna:/home/dh1 # Thanks for your continued efforts with this problem, I'll keep you posted. -- dh Don't shop at GoogleGear.com!
