Hi, i just booted a recent knoppix-cd (4.0.2) and i'm trying to enable DMA, but it won't work!
I started qemu with that command: qemu -m 256 -cdrom knoppix.iso -boot d But inside knoppix, a "hdparm -d1 /dev/hdc" won't work: HDIO_SET_DMA failed: Operation not permitted Are there some issues with qemu's DMA support and Linux? (qemu does have DMA support, doesn't it?) Greetings Sven
