I detect some confusion here....
There is no Linux 6.0 or 5.0 we are still working with Linux 2.2.xx (or
2.3.xx if you are brave).
The 6.0 / 5.0 may be RedHat versions in which case you should be using
6.1 for a 2.2.xx kernel.
In any case You MUST get a clean Linux source tree from somewhere like
ftp.us.kernel.org
Then you patch that with the Real time mods.
I normally make menuconfig and select HARD REAL TIME SUPORT.
But this option only shows up After you have patched the kernel.
After that you still have to make dep; make clean; make bzImage ; make
modules; make modules_install;
Then you have to:-
o copy arch/i386/boot/bzImage to /boot/bzImageRTxxx
o edit lilo to add /boot/bzImageRTxxx as a boot option.
o cp System.map to /boot/System.mapRTxxx
o ln -s /boot/System.mapRTxxx to /boot/System.map
o Check with ls -l /boot/System.map
o run lilo only then can you reboot.
o You still may have a problem with Ethernet not coming up and you have
to do a /sbin/modprobe eth0 in /etc/rc.d/rc.local
Phew...
