Tell him to press the Big Red Button (reset button, even if it isn't red).

You can be pretty sure that the addresses and such are OK. The problems in this area are generally a matter of timing, and since the timing isn't documented, it's difficult to guess how a particular machine will react. This isn't just a FreeBSD problem, BTW. Most PC UNIX implementations have it, and commercial products like UnixWare seem to have the most trouble. Greg
