VME: Reload sis1100 (needs root access)

To avoid a reboot of an ExpPc or just for testing purposes one may reload the VME driver by hand:

pXXuser> tango stop
root> rmmod sis1100
root> dmesg
[3702239.073548] sis1100 driver exit
root> modprobe sis1100
root> /usr/sbin/sis1100.init start
  this will produce error messages like: 

    root@haso107d1:~# /usr/sbin/sis1100.init start
    Creating device files for sis1100-e 
    sis1100 major: 248
    ln: failed to create symbolic link '/tmp/sis1100_015dsp': File exists
    ln: failed to create symbolic link '/tmp/sis1100_014dsp': File exists
    ln: failed to create symbolic link '/tmp/sis1100_013dsp': File exists

  they can be ignored.

This is what dmesg shows, if the VME crate is OFF or ON:

If VME is OFF
