Very Computer

Hi all,

I've searched and searched on how to get DMA working on my harddrive,
but it's still not working :)

I'm running a Gigabyte 8IPE1000 mobo, which is based on an Intel 865PE
chipset. The controller is an ICH5.

I've got a SATA Seagate 160GB 7200.7 which runs beatifully (50MB/sec),
but the PATA Seagate 80GB Barracuda V (/dev/hdd) runs like dog's
bollocks (2MB/sec).

beast:/home/scottr# hdparm /dev/hdd

/dev/hdd:
  multcount    = 16 (on)
  IO_support   =  0 (default 16-bit)
  unmaskirq    =  0 (off)

Problem is, when I try to enable DMA I get:

beast:/home/scottr# hdparm -d1 /dev/hdd

/dev/hdd:
  setting using_dma to 1 (on)
  HDIO_SET_DMA failed: Operation not permitted
  using_dma    =  0 (off)
beast:/home/scottr#

I've compiled my own 2.6.6 kernel after downloading the source deb from
the Debian archive.

I've selected the follwing options, which I read that I needed from many
many sources:
CONFIG_IDE_GENERIC = y
CONFIG_BLK_DEV_IDEPCI = y
CONFIG_BLK_DEV_GENERIC = y
CONFIG_BLK_DEV_IDEDMA_PCI = y
CONFIG_IDEDMA_PCI_AUTO = y
CONFIG_BLK_DEV_PIIX = y
and also for the SATA support:
CONFIG_SCSI_ATA_PIIX = y

I'm pretty sure this is all I need - am I missing something? I'm running
an up to date Debian Sarge. Or is this an issue I should be taking
somewhere else?

Any help is appreciated... I'm what you'd call an advanced Windows user
who's trying desperately to migrate, but this is slowing things down a
bit :)

Cheers,

Scott Raynel.

Thanks again,

Scott.

It covers the ICH5 chipset , hope that helps.

Thanks for the info. However, the SATA drive is running well - it's the
PATA drive that I can't seem to get working properly. I might have to
bite the bullet and re-install onto the SATA drive instead. I hear the
Debian Installer beta4 has support for SATA and kernel 2.6. Has anyone
had any experience with it? Especially if you are using an ICH5 chipset?

Thanks again,

Scott.

Here's the fix for anyone who is stuck...

I'm using a Gigabyte 8IPE1000 motherboard, and I had SATA Port 0 mapped
to the Primary IDE channel.

Doing this means that you can't enable DMA on the Secondary IDE channel
either, which is what I was trying to do, so getting rid of the mapping
and changing it back to SATA Port 0 meant that I could set up DMA on my
Primary and Secondary IDE channels. I'm now enjoying 46MB/sec reads off
the PATA drive, and 54MB/sec off the SATA.

The reason I had the SATA drive mapped to the Primary IDE channel was
because I wanted to have the SATA drive as my C: drive in Windows, and
when it installed it set C: as the Primary Master drive, so I had to
remap it. After installing it, I was able to change it back to the SATA
Port setting and Windows was fine.

Hope this helps someone,

Scott.
