On my Toshiba P35 laptop, opensuse 10.2, *nothing* is shown in Yast IDE DMA Setup. Is this normal???
Additional explanation, when I say nothing is shown in Yast IDE DMA Setup, I literally mean *nothing* not just no DMA option, I mean *no* hard drive at all. That's what is really strange...
It might not be enabled, try the command hdparm -d /dev/hda to check if it is enabled (you need to be root to run this command). If it is not, you can enable it with the command hdparm -d1 to enable it. The man page gives more information on the command. Also, it wouldn't hurt to check the BIOS settings.
That is another strange thing about this laptop, the bios is virtually void of any information. I mean yes, it shows the drive and basic time/date information and has the ability to set the boot device, but that is about it. There is a lot of stuff that just isn't shown/configurable. This P4 laptop is aging yes, but as far as function it has integrated 802.11g, firewire, usb, dvd-rw, multicard reader, etc. but is has the smallest human bios interface known to man - go figure? Maybe that is why Yast doesn't show the drive and why nobody has configured a powersave suspend to ram acpi function.
Thanks for the help. If you have any other thoughts, please pass them along!
I rarely use yast, as I perform most tasks from the command line. On my laptop, I noticed that it was using the 16-bit default for transferring data from the ide controller to the bus. You can check this with the hdparm -c /dev/hda command. While nothing can be done about the 16 data transfer lines on the cable, you can improve the bus transfer by setting the value to 1 or 3. Read the man page on this one, as some chipsets want the value to be 3. Changing the bus transfer size does provide a small boost to performance. You can test the results, with the command hdparm -Tt /dev/hda.
