When I try that sysctl command I get this: # sysctl hw.ata.atapi_dma=1 sysctl: oid 'hw.ata.atapi_dma' is read only The same thing shows up at boot when I have the 'hw.ata.atapi_dma=1' part in /etc/sysctl.conf Charles, I appreciate all your help so far, and I hope that I'm not frustrating you too much.
