Can not autoload driver in boot time

[JV]

Hi!

Can not autoload my drivers in boot time. All the RTAI modules loads
great at boot when I added modprobe lines in /etc/rc.local, but now
autoloading drivers are causing problems. I have tried allready add
these lines

alias char-major-98 comedi
alias char-major-98-0 your_driver
post-install your_driver /usr/sbin/comedi_config /dev/comedi0
your_driver <<options>>

to modules.conf file. Also there is in 3 places(/usr/local/sbin/, /usr/
local/src/sbin/ and /usr/local/src/comedilib/) in filesystem
comedi_config and tried all but did not work. Can anyone help me?

And now can!
Easiest was to put insmod,modprobe and comedi_config lines in rc.local
file. Modules and drivers are loaded nicely at boot!!!
Tried several different places to add alias lines, but could not get
working. Solution was actually easy. File rc.local will be run every
time I boot and you can add shell commands to it.

Yes, the main problem with autoloading is that RTAI installs its kernel
modules in /usr/realtime/modules by default, which is outside the
kernel's autoload path.

It's possible to configure RTAI to install its modules somewhere else
using its --with-module-dir=<path> configure option. For example, the
modules could be installed to /lib/modules/${kernelrelease}/rtai/ (where
${kernelrelease} is the `uname -r` value for the kernel).
Unfortunately, there is no way to specify this in the RTAI configuration
menu (at least not the last time I looked), but it is possible to set it
when using the ./configure program instead of "make menuconfig".
