I running debian linux on an old box on which I just built 2.6.6. The manufacturer lists the chipset as:
AMD 750, consisting of the AMD 751 Irongate North bridge and the AMD 756 Viper South bridge
I am trying to enable DMA for the harddrive with no luck. I get the output:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
Most posts regarding this say that this happens when the chipset drivers are not built into the kernel. However, I have been unable to find this chipset in the kernel config. The only place it seems to show up is under apgart options, which doesn't help. The drive is IDE and the only drive on the cable. It is jumpered to Cable Select. Any ideas about how to fix this? Thanks!
