1.  Check if the definitions  in "mvv_parms.h"  
      #define ProMoviePort 0x250
      #define ProMovieIRQ  12
      #define ProMovieAddr 0xc8000
    are appropriate for your system; using 
    the same ones you do under DOS is a good start.  If you don't 
    know what they are, you probably shouldn't be playing with
    alpha device drivers.

2. Check if your system and display support the Shared Memory Extension, which
   would *significantly* improve the live video performance.
   Use the command "xdpyinfo" for this.
   If SHM is supported, you should enable the "ifeq ($(SHM),TRUE) " section
   in the Makefile by setting SHM = TRUE

To use the interrupt driver you have to do following steps:
(The program works also without it as a first try)

1.  As root, type "mknod /dev/fg c 31 0".  The 31 should match
    the definition of FG_MAJOR in the irq_driver.c source code.
2.  You should check which source for video input you use 
    (Composite or S-video) and set "ProMovieSource" in irq_driver.c 
    accordingly. Otherwise you have to set this from the "MVV set" menu.
    (An popup menu of PMS-view)
3.  Just run "make install" and you should get a loadable driver
    that will be installed

You don't have to use this driver, without it the viewing loop simply polls
the frame grabber device, which means that captured frames sometime appear to 
be divided if the scenes change quickly. 

If the installation failes you probably have a root password set. 
Then you can install it per hand as root with the command
  "insmod irq_driver.o" 
The message :
"irq_driver: No such file or directory"
that appears for the first install (rmmod) can be ignored.

If you have installed the driver the grabbing is driven by the interrupts.
Then you should set a frame rate that is not higher than the display. 
You are warned if it is, though. 

At last you can run the view program PMS-view, with 
"make PMS-view" and start "PMS-view" . It must be run with SUID-bit set,
which is automatically don from make.
