If you want to try it, google for a MS-DOS boot disk image to download, either for floppy disk or CDROM depending on what hardware you have. > > The main reason I'm concerned about this bug is that I'm planning on > building my own machine and possibly running FreeBSD on it for my > research.

The acpidump/iasl combo is FreeBSD's way of working round it. You might want to try on the acpi mailing list if you want to investigate further. I think the acpi section in the handbook says they like to know about such problems. I don't think it is a common problem. If you are buying a new motherboard you should be able to find something without this problem. Check the hardware notes http://www.freebsd.org/releases/8.0R/hardware.html Chris
