Support for 80386 processors (the I386_CPU kernel configuration option)

2006-01-09 Thread zimmermanjj
Hello.  I quoted the subject of the email directly from the kernel changes 
section of the FreeBSD/i386-RELEASE release notes.  I am not sure if I am 
reading this correctly, but does this mean that people who have Intel-based 
processors (such as P4 and Celeron) should not use 6.0 and only use 5.4?  I 
want to intsall FreeBSD 6.0-RELEASE on a Celeron and a P4, and to the best of 
my knowledge they are i386 processors (80386).  If someone could clear this up 
I would appreciate it.

Of course, not!

It means that 486 and latter processors are supported.

You are referring to a processor family.  The release notes refer to a
particular CPU/processor type.

I'm running 7.0-CURRENT on a Celeron system at home.  You shouldn't have
problems running any version on your CPU, from 4.X, to 5.4 or 5-STABLE,
or evel 6.X.

No, P4 and Celeron are not 80386 processors. They are descended from the
80386 and belong to the i386 *family* of processors, which is a slightly
different thing.


What has been removed from 6.0 is the ability to run on an *actual* 80386
CPU.  They were state of the art in the late 80's, but that is a while ago.
If your computer has a clock frequency of 50 MHz or more, it is almost
certainly not using a real 80386. (If I remember correctly they were
only available in speeds ranging from 16 MHz to 40 MHz.)

FreeBSD 6.0 should run fine on any Intel CPU from the original Pentium and
onwards. (Also on an 80486, if it has an hardware FPU - either built in or
external.)
