The kernel I'm using is 2.4.20-8(RH9) now.
linux kernel source is /usr/src/linux-2.6.8.1
rtai source is /usr/src/rtai-3.1

The step I tried is:
1) cd /usr/src/linux-2.6.8.1
    bzip2 -dc ../patch-2.6.8.1.bz2 | patch -p1   // linux patch
    patch -p1 </usr/src/rtai-3.1/rtai-core/arch/i386/patches/hal7-2.6.8.1.patch    // rtai patch

2) make menuconfig  // congfig the linux kernel

3) make -f ../rtai-3.1/makefile srctree=../rtai-3.1  // execute the command in README.INSTALL

Then it showed an error:
configure: error: Please unset CONFIG_MODVERSIONS for /usr/src/linux-2.6.8.1 and rebuild your kernel

What does this error mean? And what should I do?

And what to do after step (3)? Is it all done after that, and what I need to do is just reset my PC?
