I've not seen any, but I suppose they exist. The TAPR ones, however, definitely are not those beasts. they are simple and don't support hotswap. : Plus, it is actually curious that you can fry the IDE controller, : the simplest ones used to be just a couple of '245 and an : address decoder... I think that the main problem is lack of good grounding causing large transients when the card is removed. But I could be wrong about that. Each time I fried one it was definitely a remove + insert sequence. Warner To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
