If this is the case, then the hardware notes need updated, I quote: "All Intel processors beginning with the 80386 are supported, including the 80386, ..." ... and ... "While technically supported, the use of the 80386SX is specifically not recommended." That last sentence is slightly vague. I assume that they recommend against the 386 simply because it's not powerful enough to be worthwhile, but it doesn't say specifically why. > > Tom Veldhouse > > ----- Original Message ----- > From: "John Nielsen" <john@jnielsen.net> > To: <questions@freebsd.org> > Sent: Thursday, June 12, 2003 2:25 PM > Subject: 5.1 on a 386 > > > >>Hi folks- >> >>I am setting up FreeBSD 5.1-RELEASE on a 386DX.
