It's possible to do; you probably want to limit it to a "test drive" CDROM, rather than putting it into a production setting. The issue is that the MTBF for IDE CDROM drives is very low, comparatively, when they are forced to a continuous duty cycle. This was discuseed two years ago, and I don't think the situation has improved any. 8-(. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
