New releases of Linux

Post by Pat Pridge » Fri, 11 Feb 2000 04:00:00



Are all of the New Releases of Linux (RedHat, Slackware, Debian, etc)
optimized for Pentium machines? I've been looking at a CD pack on
cheapbytes, and if all of this isn't going to run that well on my 486
then I'm wondering what would be my point of getting these later
releases. The version of RedHat that I'm running works fine, but...It
would be nice to have the later libraries for some programs that I would
like to run. Trying to ftp them has been very disappointing, due to my
ISP and stalls on ftp.

Thanks for any information you can provide.

Debian is not.

Usually programs "built for Pentium" will not run on older processors.

I believe this is just a matter of which kernel you use.  There
are specific kernels for i385, i586, and i686.   If you install
RedHat for example, it figures out which processor you have and
installs the appropriate kenrel.

The major problem with the more recent releases is that they
require considerably more disk space.  If you have limited disk
space, you may have to work hard to get a collection of packages
which fit on your machine.

You could try to upgrade and make sure you eliminate any packages
which either won't fit or will run very slowly.   I suspect
you would have trouble either with KDE or Gnome.

No.  Debian will run fine on your 486.

As faras I know, only Mandrake is. That is the i586 rather than i386.

No. Most are compiled for 386 for the simple reason that linux can run on
386 and 486 machines.

Mandrake is the only one I know of that is.

With SuSE at least, that's a pretty simple matter.
I installed my first distro (SuSE 5.2) on a 200 Meg drive (32 meg swap
partition).

Now I'm running with about 1.1 gig on SuSE 6.2.

Most of them are compiled to use the i386 CPU. Both SuSE 6.2 which I
tested
and Slackware 4.0 and 7.0 use kernel compiled for i386.
After installation you can recompile the kernel to use the CPU on your
box with some improvement in performance. Hardly noticeably in single
user case.

The best fix IMO for this would be while installing a linux distrubution
from a new cd add the kernel sources and base that way you can adjust your
kernel to optimize it for your system completely from everything from
processor to ethernet card. the best place to start learning about your
kernel configurations would be the kernel how-to (ussually disributed with
the ussual releases) and start enjoying your newly found headaches :-) have
fun and if your connection ever improves you can start to download the
latest greatest kernel from www.kernel.org and not have to buy the latest
cd every time it comes out except for severly saved time in downloads.

The only mainstream distro that I know that is Pentium-optimized is
Mandrake. Red Hat, Slackware, and Debian will work fine on your 486.

There's also Stampede.

i386, i486, i586 share the same instruction set (as far as gcc is
concerned).  i686 machines add a few new opcodes (like cmov) and thus
code targetting them might not run on older ia32.

be advised that i586 is classic pentium and classic pentium mmx.  the
i586 is a weird beast and optimized code for the i586 will not run as
well on other machines.

i686 machines (pentiumpro, pentium-ii, pentium-iii, xeon, celeron) are
*hurt* by scheduling for i586 as opposed to scheduling for anything
else, e.g., i486 (which most distributions do), nevermind actually
targetting i686 proper.

running benchmarks (from gcc-2.95.2 code) on my pentium pro generally
say things like

target     time units
i386          1.05
i486          1.01
i586          1.20
i686          1.00

thus it doesn't matter if the target is i486 or i686, but i586 slows
me down by 20%.

mandrake's targeting of i586 is actually bad for anyone without a
classic pentium.  i am baffled as to why they do it.   the last
classic was made over two years ago.

How about target i586 with a K6?

offhand, i would say it's a bad plan.  the i586 has a weird dual
pipeline structure.  speed scheduling for the i586 involves doing some
stuff in round-about ways to keep both pipes full.  most later
processors have a built-in peephole optimizer to do this step on the
fly.  i think the latest gcc have amd-k6 scheduling.
