This is not unreasonable; they are probably using an SMI handler for this. That's fine; they should still be using DMI to export the information in question. > Gigabyte MB's are cost effective and have a good reputation from people on > this list; however, it would appear that contrary to their marketing > rhetoric ACOPS is a closed-door solution that is a win only for MS$ users > who can realize the unmitigatably overwhelming benefits of Gigabyte's > bundled patented SIV application. Supermicro, ASUS, Tyan and Tekram are all other manufacturers to whom you can look for server-grade boards. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
