Please post the output of:

hdparm <the disk in question>
and
hdparm -d1 <the disk in question>

Kind Regards Bjerrk

hi
here it is:

Code:

root@slack2:~# hdparm /dev/hda

/dev/hda:
 multcount    = 16 (on)
 IO_support   =  0 (default 16-bit)
 unmaskirq    =  0 (off)
 using_dma    =  0 (off)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    = 256 (on)
 geometry     = 48641/255/63, sectors = 781422768, start = 0

Code:

root@slack2:~# hdparm -d /dev/hda

/dev/hda:
 using_dma    =  0 (off)

Code:

May 20 00:37:02 slack2 kernel: ReiserFS: hda1: warning: CONFIG_REISERFS_CHECK is set ON
May 20 00:37:02 slack2 kernel: ReiserFS: hda1: warning: - it is slow mode for debugging.

Where is special option in kernel configuration to enable DMA by default.
device drivers - ATA/ATAPI/MFM/RLL support (kernel 2.6) - Use PCI DMA by default when availible.
If it not helps try to recompile kernel with your chipset support with disabled "Generic/Default IDE support".

masterross · 05-20-2006, 05:50 AM

yes i need the right chipset driver
unfortunately i dont know which to use

can you help me?

thanks!!!

masterross · 05-20-2006, 04:06 PM

now even cannot detect HDD

((((
and when i do make:

Code:

drivers/ide/pci/generic.c:45: warning: 'ide_generic_all_on' defined but not used

help plz !!!!

i'm desperate!

i think you should use Intel PIIXn chipset support because
http://lists.debian.org/debian-user/.../msg03903.html
and
<*> Adaptec AIC7xxx Fast -> U160 support (New Driver)

If you don't need it disable reiserfs debug mode. it slows down system. just leave reiserfs support.

Warnings is not ERRORS. So just relax while your kernel is compiling.
