Re: Dvd,dvd,dvd...

Hi,
I totally forgot about loader.conf, now the drive gets set to UDMA4 on 
boot. Its strange, but mplayer still fails on UDMA4, although I can 
mount the dvd no problem. So added the atacontrol command to rc.local.

Im sure the drive can handle UDMA4 since I remember that in Linux this 
drive worked perfect in UDMA66 + the manufacturer lists UDMA4 as a 
supported mode as well.

I havent been able to replicate the crash yet after a reboot, but if it 
happens I'll let you know.

Cheers
Petr
