Trouble Enabling DMA Mode on IDE Drive
Posted by GriffinRUN, 04-23-2009, 12:14 AM I cannot enable DMA mode on /dev/hda when attemping to enable it via ssh I am running CentOS 4.7 and cPanel 11. cPanel also shows DMA is not enable on this drive. Kernel: 2.6.9-78.0.13.ELsmp Anyone have any idea how I can fix this? Thanks
Posted by DigitalLinx, 04-23-2009, 12:27 AM Most probably you're missing the chipset module for your motherboard so DMA is not enabled, believe you must recompile the kernel enabling the proper IDE interface chip module.
Posted by aibo, 04-23-2009, 12:27 AM I believe you have to enable the chipset module for your motherboard in the Kernel configuration. Run the 'lspci -v' command, from the output try to find the name/vendor of the IDE interface chip.

Posted by aibo, 04-23-2009, 12:46 AM That looks like a SATA Controller. Any other IDE Interface?

Posted by aibo, 04-23-2009, 12:52 AM Did you enable DMA support in Bios?
Posted by david510, 04-23-2009, 03:40 AM What is this showing? cat /proc/ide/hda/settings When you try to enable it what does /var/log/messages say?
Posted by GriffinRUN, 04-23-2009, 04:23 AM I did not see anything relating to DMA in /var/log/messages
