What is diffrence between I386 and I486?


Trying to figure out what kernel to compile for slackware10.2 but I don't know what the difference is between I386 and I486 hardware systems. Thankyou

Each are intel processors and the predecessors to intel pentium class cpu's. Unless you have a very old machine, you likely have neither.
if you have a newer CPU (P4) you likely need to look for i686

cheers

Virtually all computers you will be able to find today are i686 (Pentium II and newer)

I'm pretty sure the pentium pro was the first i686... then on up to the pIII in the intel line...

You're right, amosf; Pentium Pro and up.

Yeah so this makes me curious.
If I type "uname -rm" I get the response:
2.6.8-2-386 i686
I installed the 386 kernel package from Debian, but am running on a 686. Does this lead to problems?
Must b I'm a

EDIT: Yeah that's probably kind of a dumb question. I'll just read up on it and test out the 686 version to see what happens.

Newbie so not sure if I'm in the right thread.
Installed RH9 2 weeks ago. Just sorted out registration problem with up2date and did update. Have an i686 but it seems that I've somehow updated to i386 kernel. Does that make sense? Anyway, is this going to cause a problem? Should I try and locate a kernel for i686 and update again? or should I take this opportunity and opt for another distribution like Slackware 10.2?

i386 refers to the base system that the code will run on. Anything above that will run it just fine.

I'm now convinced that running the 386 kernel on my 686 machine was causing a problem which is discussed in another thread: http://www.linuxquestions.org/questi...d.php?t=362259
