Getting DMA enabled on the intel 7500 chipset

Getting DMA enabled on the intel 7500 chipset

Post by GNUOrde » Sat, 21 Sep 2002 02:02:24



I have 2 remote servers I'm trying to get DMA enabled on.  Both are the
tyan Thunder i7500 (S2720) motherboard running redhat7.3.  Both have the
latest BIOS which is suppose to fix the problem but didn't.  From
searching the archives and talking to people, its a known problem that is
fixed in one of the -ac patches to 2.4.19.  I've tried several patches
myself and it seems to fix the DMA but when the init scripts start they
get a lot of file not found and never comes fully up.  I used the some
config from the stock redhat kernel, 2.4.18-3 for 2.4.19 (which works fine
other than the DMA problem) and the patched 2.4.19-acx kernels.  I also
tried the script in the kernel tree that is suppose to apply all the
patches I thought.  It only applied the latest patch which did not work.
It is at least access the root file system.  BTW, I had to mkinitrd images
myself in most cases but in one case, make install seems to have made one.
 The modules are out there in their correct places,
/lib/modules/2.4.19-acx.  Lilo knows to load the initrd image, I copied
the same section as for the 2.4.19 entry that works and changed the names
of everything to match the test kernel. Anyone know of what could be
happening to keep these kernels from starting up properly? Thanks for any
input

1. Enabling DMA on an Intel 856PE chipset.

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

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.
