I tried removing it from the loader.conf file and after boot the value was still set correctly. The confusing bit is that we can set the speed using atacontrol but it doesn't get set at boot. > Also, I get from the Zip drive: > ata1-slave: FAILURE - SETFEATURES SET TRANSFER MODE status=1 > error=4 I haven't seen this one. I think I'll turn on verbose booting and see if I see something similar from the DVD drive. I'll pop in the modular drive too to see if it gets set properly. Sean
