Hello,<br><br> I built CLFS-SVN-2070923 Pure64 using LiveCD-x86-6.3-r2052 as host back in September.<br> I just realized that my DVD device is being recognized and handled in such a way that I cannot update the DMA mode of it using hdparm. It is an IDE/ATAPI device (/dev/hdb).
<br> When trying the hdparm command I get the following,<br><br>"root@familia# hdparm -d1 /dev/hdb<br><br>/dev/hdb:<br> setting using_dma to 1 (on)<br> HDIO_SET_DMA failed: Operation not permitted<br> using_dma = 0 (off)"
<br><br> If I try the same command after booting from the LiveCD, I can change the DMA mode without any error or warning.<br> I have no clue how to resolve this. I followed the book instructions when I built the system.
<br> Any advice is appreciated<br> Thanks,<br><br>Alonso<br>
