hello. I have an enhanced ide motherboard with a new fujitsu 20 gbyte harddrive. When I try to enable dma on the drive the following is reported: /dev/hda: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off)
Is this because the ide controler ( on board) doesnt support dma? How about to change the pio modes? when I try to change to pio mode 2 ( I know it is supported by both the drive and controelr) the following is reported: /dev/hda: attempting to set PIO mode to 2 HDIO_SET_PIO_MODE failed: Function not implemented can any body tell me why all these error occur? I have kernel 2.4.1 thank you
