Hi Kay,

Oops missed that.  Thanks for your help on this.  I've got it working now :o)

Another question for you ;o)

I've noticed that there is a devfs udev rules file, but it says not to use it as devfs compatibalty 
isn't really the way to go.  I've also noticed mandrake & others all seem to use it.  Is there a 
standard defined somewhere which lists what device name/symlinks you should use for likes of ide 
devices & others?  Either I try to get the devfs script file working, or recode several different 
scripts.  Both is about the same amount of work as the script doesn't work on busybox ash.

Also, I don't want to have to recode things again later on so are trying to work out the best way to 
do it now.

Thanks

Miles
