You can check if DMA is enabled on a device with idetool. Here is how it works here but you have to change ide device name of your machine:
8.Workbench:> idetool -l peg2ide.device -------------------Unit 0 information------------------------ Flags : $000001A7 - present, LBA48 used, supports DMA, ATA, supports acoustic mgmt, supports cache flush, interrupts used, Xfer mode : best pio 12 (PIO 4, 16 MB/s) / best dma 69 (UDMA 5, 100 MB/s) / current 69 (UDMA 5, 100 MB/s) Total blocks : 398294975 Blocksize : 512 Power mode : 2 / idle (ready for operation) IO1 / IO2 / BMCR @ : $1000 / $100E / $1020 spurious interrupts: 0 bounced misaligned cache line start DMA requests: 447 bounced misaligned cache line end DMA requests: 0 bounced non-contiguous buffer DMA requests: 26 -------------------Unit 1 information------------------------ Flags : $00000187 - present, LBA48 used, supports DMA, ATA, supports cache flush, interrupts used, Xfer mode : best pio 12 (PIO 4, 16 MB/s) / best dma 69 (UDMA 5, 100 MB/s) / current 69 (UDMA 5, 100 MB/s) Total blocks : 976773168
