Oops, soory, that should be 'devinfo'.

Yuck, performance is going to be sucky. Bad Tyan, no cookie. That'll also explain the limited number of interrupts available. I don't think there's anything we can do to help the situation, sadly. > The server runs i386 version of FreeBSD (5.3-RELEASE-p5) since > I experienced some problems building ports on amd64 version. You probably need to use the hw.physmem="2G" loader tunable to get 5.3-R installed.
