Does CentOS support NCQ on SATA drives? If so is there something I must do to turn this support on? Matt

CentOS 5 should have at least that version of kernel (RHEL5 beta 2 uses 2.6.18). There's always probability that RH will backport it to 2.6.9. -------------- next part -------------- A non-text attachment was scrubbed...
