I have newest Knoppix 3.4 and installed kernel-source-2.6.5 from Debian unstable and changed symlinks to point to the new source.

When installing ndiswrapper there is no problem with make install:

Code:
root@abc:/home/tapsa/ndiswrapper-0.7# make install
make -C driver install

Even installing Windows XP drivers (Linksys WMP11 v. 2.7 with Broadcom chipset) went fine:

Code:
root@abc:/home/tapsa/ndiswrapper-0.7# ndiswrapper -i /lib/windrivers/wmp11v27.inf
ls: /etc/ndiswrapper: Tiedostoa tai hakemistoa ei ole
Installing wmp11v27
root@abc:/home/tapsa/ndiswrapper-0.7#
Code:
root@abc:/home/tapsa/ndiswrapper-0.7# ndiswrapper -l
Installed ndis drivers:
wmp11v27        present
root@abc:/home/tapsa/ndiswrapper-0.7
But when trying to load module ndiswrapper difficulties begins:

Code:
root@abc:/home/tapsa/ndiswrapper-0.7# modprobe ndiswrapper
FATAL: Error inserting ndiswrapper (/lib/modules/2.6.5/misc/ndiswrapper.ko): Invalid module format

Code:
root@abc:/home/tapsa/ndiswrapper-0.7# dmesg | grep ndiswrapper
ndiswrapper: version magic '2.6.5 SMP preempt PENTIUMII gcc-3.3' should be '2.6.5 SMP preempt 386 gcc-2.95'
root@abc:/home/tapsa/ndiswrapper-0.7#
As you see before I have changed processor type to Pentium II with make menuconfig.

Is it possibly to install ndiswrapper without compiling kernel afresh without multi-processor support?

I have used ndiswrapper with previous Knoppix 3.3 versions by copying beforehand compiled kernel with success. But now I would like to use Knoppix's own SMP kernel. Is it possible somehow?
