hi all, iv got a 40GB hdd....by doing hdparm -d1 /dev/hda..im not able to turn on the dma settings and that is afecting the performance of my linux box...

# hdparm /dev/hda

/dev/hda:
multcount = 16 (on)
IO_support = 3 (32-bit w/sync)
unmaskirq = 1 (on)
using_dma = 0 (off)
keepsettings = 1 (on)
readonly = 0 (off)
readahead = 256 (on)
geometry = 16383/255/63, sectors = 40020664320, start = 0

i was able to increase the buffered disk reads fro a pathetic 1Mb/sec to 3 Mb/sec...by switching on unmaskirq n etc, but dma is not happening.....

#hdparm -d1 /dev/hda

/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)

plz advise..its frustating working in such slow speeds

Regards,
Danish

What kernel version are you running? I believe the later 2.6.x kernels fully supports the Radeon Xpress 200 chipset.

i just dont know what is wrong..ive googled a lot during the last days..and there has been so much that iv come across..im just not sure whats wrong...one thing more..during the boot up process...
why does my linux box search for more ide's than the one already provided...

#uname -r
2.6.9-1.667

I know this is an old thread, but I'm having the exact same issue with the same motherboard, kernel 2.6.16 using RHES4. Using the same kernel on other hardware without a problem.

Does anyone know if there's a bios setting or something that's doing this??/

Peter Larsen
