Thanks VERY much!

if you do an expert install it will give a choice afaik.

Actually, fyi, it doesn't. The only choices it gives are between a 2.4
and a 2.6 kernel for -386.

Hi Folks,
I know I must be doing something very silly, but my brand new
installation
is only finding 1gig of the 4gig of ram installed in my brand new
server.
Even if I stick a "mem=4096m" line as a boot option, it's still not
showing up. (the only suggestion I've seen in the reference
materials).
Any suggestions?
Which kernel do you use ?
I saw the same thing with a default i386 kernel.
When I switched to an i686-smp one (Xeon HT), I saw the light...
Hum, the RAM !
I'm using the out-of-the-box i386 2.6 kernel that comes with the
Sarge installer.
So I guess I have to build a kernel? Sigh...
Thanks,
Miles
you can just apt-get a new kernel
apt-cache search kernel-image-2.6 will show you the list of
available kernels, just pick the one that is right for your system
ok - thanks to all who responded - looks like I'm currently running
2.6.8-2-386
CONFIG_EDD=m
CONFIG_NOHIGHMEM=y
# CONFIG_HIGHMEM4G is not set
# CONFIG_HIGHMEM64G is not set
which explains a lot
looks like
kernel-image-2.6.8-2-686, or
kernel-image-2.6.8-3-686
would be appropriate (I'm running a P4, single processor)
any particular reason to go with one or the other?
the -3 is more up to date, so probably a good idea.
and, a few newbie questions:
- any idea why the installer only gives the -386 kernel as a choice?
if you do an expert install it will give a choice afaik.
- the 2.6 kernel off the Sarge installer comes with SATA, md, and LVM
support - will the -686 version as well?
should do
- what's the specific procedure for replacing my current kernel and
initrd with the new one - is it just an apt-get install, or is it more
complicated?
apt-get install $newkernel |
reboot
apt-get --purge remove $oldkernel

If your processor is a 686 compatible, use the i686 from sarge !
If you have an athlon, use the k7 one.
There's more than one "out-of-the-box" kernel in sarge.
Type :
# aptitude show kernel-image |

what kernel are you using? |
check /boot/config-$kernel
see:
jeffd@proto:~$ grep CONFIG_HIGHMEM /boot/config-2.6.8-2-386
# CONFIG_HIGHMEM4G is not set
# CONFIG_HIGHMEM64G is not set
jeffd@proto:~$ grep CONFIG_HIGHMEM /boot/config-2.6.8-2-k7
CONFIG_HIGHMEM4G=y
# CONFIG_HIGHMEM64G is not set
CONFIG_HIGHMEM=y
this is from a sarge system that i have, the 386 kernel wont support
that much memory, but the k7 will, those are the only ones I have, but
I'd bet that the 686 versions do as well.
