ATA/IDE/MFM/RLL support ---> IDE, ATA and ATAPI Block devices ---> [*] Use PCI DMA by default when available [*] Enable DMA only for disks

Thanks Carlos, I knew about this, but I was hoping there's a way without recompiling.

As for a boot parameter, yes:

ide?= [HW] (E)IDE subsystem : config (iomem/irq), tuning or debugging (serialize,reset,no{dma,tune,probe}) or chipset specific parameters.

But I think it is for the bus. not the device.

Thanks, I'll give this a try. A boot parameter would be good, as it would seriously speed up installs.

In suse 8.1, just edit "/etc/sysconfig/hardware" like this:

DEVICES_FORCE_IDE_DMA_ON="hdc hdd"

And they will be set on for you.

Thanks, this would help. I'm surprised that Yast2 doesn't show the relevant /dev/hdx devices so one can do it from there. Thanks again Hans == Download ringtones, logos and picture messages at Ananzi Mobile Fun. http://www.ananzi.co.za/cgi-bin/goto.pl?mobile

You can make the changes there.

For ide devices running as ide devices, yes. Not for devices using ide-scsi. Hans == Download ringtones, logos and picture messages at Ananzi Mobile Fun. http://www.ananzi.co.za/cgi-bin/goto.pl?mobile

No idea. I'm talking SuSE 8.1 Pro. Do you have 8.2? If I enable ide-scsi, they don't show up in Yast2's IDE-DMA module. If I put "hdc=ide-cd hdd=ide-cd" in kernel boot parameters, they do.

Yes I do have 8.2 PRO and (using grub) I only have hdc=ide-scsi in menu.lst More changes between earlier versions I guess. Ken

I thought I read that kernel 2.4.20 no longer required the ide-scsi module for one reason or another.

It's got nothing to do with the kernel. cdrecord 2.0 has ATAPI support, so it doesn't need ide-scsi. So if you use cdrecord from the command line, or if you use a GUI that understands the "dev=ATAPI:" notation (I only know of xcdroast) you can do without it

Correct. In suse 8.1 Yast does not sugest/allow dma for devices using ide-scsi. However, if you do the change on the hardware file manually, it is accepted. And, if you want to do the change during an install, in the worst case you might go to a console and use hdparm - but I don't really know if it is on the install/rescue system. -- Cheers, Carlos Robinson
