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?
Could be. At least, it doesn't report it, so it could be the cables, or could be that thing about the south bridge Geoffrey has posted here.
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...
Try to upgrade the kernel from suse first, just in case.
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
Yes, that's a script that reads from /etc/sysconfig/hardware (DEVICES_FORCE_IDE_DMA_ON="")
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
Did you notice an email on the list about that? It appears you have to add ide-cd to the initial ramdisk, or you get ide-scsi on all cdroms.
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)
Mm, all drives reject dma, so it probably is not the scsi emulation or the drives, but the motherboard-bios-software combination. It doesn't know how to handle your IDE, yet. -- Cheers, Carlos Robinson
