The only other glitch I remember was that pci_ids.h was not up to date and I may have added the extra device and vendor ids

I checked rtai 3.9 and magma to refresh my memory

smi_module.c is in /rtai_3.9/base/arch/i386/calibration but not in ..../arch/x86_64/calibration

However, magma DOES have smi_module.c in .../base/arch/x86_64/calibration

Doing a diff, they are identical, except that the x86_64 module contains a clumsy and unnecessary #ifdef in the pci_device struct regards ICH10_1
(unnecessary because it has just been defined a few lines higher up!)

looks like that is your best bet

good luck

PS Looks like we both got to the same place and our posts crossed!

OK, I've got a solution for this.

The problem is that rtai_smi.ko is in the 'i386' target set of the makefiles, which will or course be ignored for either x86 or x86_64 platforms.

The simplest workaround is to build as normal.

Download RTAI-(version) into (for example) /usr/src/rtai-3.9

cd /usr/src/rtai-3.9
make menuconfig ; make ; (sudo) make install

--- then ---

cd /usr/src/rtai-3.9/base/arch/i386/calibration
ln -s Makefile.kbuild Makefile
make; (sudo) make install

bada bing; bada boom; & the missing bits build and install themselves.

whata PITA!
I hope this post helps someone else!!!

Cheers
