the first command sucseeded and my machine seems to be stable with
it... I then tried the second command and got this...
setting using_dma to 1 (on)
setting xfermode to 34 (multiword DMA mode2)
HDIO_DRIVE_CMD(setxfermode) failed: Input/output error
using_dma = 1 (on)
I noted that it turned dma back on and left 32 bit alone... but the xfer
mode seemed to fail... it does jhowever still seem stable... thoughts?
