 Posted: Wed Feb 01, 2006 8:38 pm Post subject: [SOLVED] hdparm says Operation not Permitted |
 |
|
I tried installing hdparm but when I try # hdparm /dev/hda (for my cdrom) I get the following:
| Code: |
/dev/hda:
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
HDIO_GETGEO failed: Invalid argument
|
and then when I try to turn on the dma, I get the following:
| Code: |
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
|
I have made sure that all the chipset specific settings in the kernel are on and they are.
Anyone have any suggestions?

Sorry, I have to ask: You are doing this as root, right? 
Otherwise are you sure you cdrom has DMA? My last CDROM (don't have one now) didn't have DMA altough it was a 40x one. |

I am doing this as root. As to whether or not my drive has DMA, thats a good question. I went to Sony's site and they dont even have information on my drive.
I bought it a year ago and its a DL-DVD burner.. so I would think it would have DMA? |

What does:
give you?
And in what mode does the BIOS information screen show it as when you boot? |

| Are you sure you have enabled your chipset in the kernel? If not, recompile the kernel with DMA settings and support for your chipset (which you will find with lspci). |

When I type "dmesg | grep hda" it says
| Code: |
hda: SONY DVD RW DW-Q28A, ATAPI CD/DVD-ROM drive
hda: ATAPI 12X DVD-ROM DVD-R CD-R/RW drive, 2048kB Cache
|
I know that my motherboard uses the VIA K8T890 chipset (which isnt listed under the kernel configuration) but it says I have support for AMD and nVidia IDE and my cpu is amd.. is this wrong? |

| You need the VIA82CXXX support, methinks? My chipset is K8T800, and that's what I use. Your chipset seems similar from a quick search; VT8237 southbridge here, I think your's is the same, maybe VT8237R - but that shouldn't make any difference here... |
