I can't decide if you are being a Troll or are just too lazy to keep up with
developments.

The ability to use more than 1 GB RAM has been around for some while. RH
started shipping alternative kernels with it enabled around RH 8 AIR. It
has been used on a number of hosts running busy mail servers.

I think the majority of problems have been ironed out.

Clearly you have never used an x86 with more than 1G. If not you wouldn't
write such a useless, misinformed and plain wrong post.
> I think the majority of problems have been ironed out.

You *think*? Are you not confident on what you are writing about? You
start insulting people with pointless arguments, and at the end of the day
you *think* you are right? So why not just keep you mouth shut, and
refrain from using the keyboard for posting nonsense?
Why don't you try 3G, and then come back and tell us what problems have
you got? Come on, make me laugh, you buffoon.

Are you the troll or just the idiot that post with this same name?
Why do you think - provided you have a primitive brain of course - that
you have 2 modes in the kernel for managing memory? I repeat, since you
seem to be quite retarted: 2 modes

One for memory < 1G
One for memory betweem 1 G and 4G

Even your rudimental brain should understand that something strange is
going on, instead of having a unique version you should recompile the
kernel in order to manage larger amount of memory. Which is addressable
by x86 without segmenting.

Experience will show you (if you can understand the word, of course) that
there is a difference under x86 with less than 1G of memory, or more.

Unfortunately sometimes the behavior with more than 1G on this platform is
not very good.
Let's only hope that the OP won't see this problems.

Shady, _you_ said you didn't think BIGMEM would work (well or at all)
with x86.

Alan said that this option _does_ work, and is in fact designed for x86.
It just isn't in the standard Slackware kernel.

You were wrong, Alan was right. Insulting him won't change that (jeez
what is this, Kindergarten!?).

from the .config of 10.0's bare.i:

# CONFIG_HIGHMEM4G is not set
# CONFIG_HIGHMEM64G is not set
# CONFIG_HIGHMEM is not set

current's bare.i has the same.

So you'd have to recompile to actually _have_ support

no, i think we're seeing a +Chiron+ wannabee. unfortunately, he's not very
convincing.

let's not stop at 3GB. how about 4GB on x86? i have plenty of boxes with
that, and guess what - no problems. how's that for kicks?

For me, the less polite you are the less likely you are to understand what
YOU are talking about and the more likely you are to base your statements
on biased opinion rather than real facts.
