Hello all, I just setup a debian woody unstable on my ShuttleX : 
 
configuration : Debian GNU-Linux 2.6.11.7 woody/unstable on i686 AMD ATHLON 1800+ 
 
The Shuttle motherboard type : SN41G2 - NVIDIA nForce2-GT chipset FN41 - 1xDDR400-512Mb - Integrated GeForce4 MX core - channel sound (MCP-T 
and AC'97 codec Realtek ALC650)- PCI typical of XPC. 
 
When I'm trying to use hdparm on the /dev/hda here is a problem : 
 
kain:/home/frederic# hdparm -c1 -d1 /dev/hda 
 
/dev/hda: 
setting 32-bit IO_support flag to 1 
setting using_dma to 1 (on) 
HDIO_SET_DMA failed: Operation not permitted 
IO_support = 1 (32-bit) 
using_dma = 0 (off) 
 
the kernel .config options :
