Hi CRUXers,
I have a problem with enabling DMA for CD in my Dell Inspiron 9300.
From hdparm /dev/hdc:
/dev/hdc: HDIO_GET_MULTCOUNT failed: Invalid argument IO_support = 0 (default 16-bit) unmaskirq = 0 (off) using_dma = 0 (off) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) HDIO_GETGEO failed: Invalid argument
From hdparm -d1 /dev/hdc: /dev/hdc: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off)
This might be a stupid question, but are you running hdparm as root?
