Re: 6.2 with PAE ?
Hello,
For those who may be interested,
I found a way to use the whole system memory (>4GB) without
re-mastering the Knoppix 6.2.0 cd / dvd:
I use the iso boot solution with a new Linux kernel and initrd (using the
large model memory) and
patch a boot time the official Knoppix iso using the unionfs and a new
cloop containing the new kernel modules.
Same approach used by Klaus within the Knoppix live cd but the cloop file
is outside the iso file image.
If interested, please look at the forum for the links and I would
appreciate some feedback...

Best Regards,
Gilles
PS: This mechanism allows me to also include at boot time the nvidia and
ati (proprietary) drivers
and have vmware workstation pre-installed and ready to use with a guest
OS, all from a USB dongle.
Is there a better way to travel without a laptop ? But I cannot share
these because of the licenses...
I already asked vmware for the permission and I am still waiting for an
answer...

Hi Klaus,
Would it be then possible to offer an alternate linux kernel (and boot
menu) with PAE enabled ?
I can even see the significant benefit (about 2x speed increase) of a 64
bit kernel option
(but still using most libraries & applications in the 32 bits
compatible mode)
My two cents,
Gilles
PS: did you receive my last email ?

Sorry, no, unfortunately you will need to build your own Kernel for
this. With PAE enabled, Knoppix would no longer run on old (well,
not
even too old) computers with non-PAE capable CPUs. I have checked
frequently on this in the past time.
Therefore I still keep the non-PAE default for a while in order to
support the widest possible range of CPUs with a single kernel.
You can find the kernel sources at
http://debian-knoppix.alioth.debian.org/packages/linux-source-2.6.31.6_2.6.31.6-10.00.Custom_all.deb
http://debian-knoppix.alioth.debian.org/sources/cloop_2.631-1.tar.gz
When rebuilding the kernel, please make sure that you select a CPU
newer
than 586, and then you can select the PAE memory model.
