Cannot Set DMA via hdparm

Cannot Set DMA via hdparm

[Alex]

Hi,
I am having problems settng the DMA ( hdparm -d1 /dev/hda ) on a RH9 
2.4.28 Linux machine.
I always get the following error messages:

HDIO_SET_DMA failed: Operatopm mpt @er,otted
using_dma = 0 (off)

The Disk ST3120026A is properly recognized. It appears that the 
motherboard is not supported. ( I am running linux on a Shuttle XPC with 
the ATI Radeon 9100IGP / IXP150 Chipset.

Has anyone an idea how to get this dma setting work ?
Will that chipset be supported in the future ?

Thanks
Alex

I assume you are talking about 2.4.18?

It seems some experimental support for your chipset was added in later 
2.4 kernels.

Could you try whether kernel 2.4.24 with the alim15x3 driver available 
in the kernel configuration at

  ATA/IDE/MFM/RLL support
    ATA/IDE/MFM/RLL support
    IDE, ATA and ATAPI Block devices
      PCI IDE chipset support
      Generic PCI bus-master DMA support
      ALI M15x3 chipset support

works for you?
