`VBR'  is  a  program  written  by  Martin Berndt which, if run in on Amiga
installation  based  on the MC68010 CPU (and successors), will relocate the
interrupt  vector  table  to fast ram which can improve the performance and
speed of the serial.device driver.

                        Usage (Shell only): VBR [?]

   The first call to this command will relocate the interrupt vector table,
the second call will restore it to its original location.  Entering `VBR ?'
will display the current vector table location.
