     Well, that happens once in 25-30 boots, it's a bug in the OS and we
will have to live with him until 1.4 comes out. BTW, this was discussed here
in c.s.a.t a while back.

     That is exactly what I do. After getting bored of waiting for a
long boot just to discover that I was left with a NTSC screen, I've wrote a
tiny little program that does what you describe. So, for a long while now, my
first command in the startup-sequence is 'reset'.

     Well, that won't be necessary. I've uuencoded my reset program and I'm
sending it at the bottom of this article. It's so little, that I guess nobody
will mind.
     Just give your friend my greetings.

     As I said, it's a bug in the OS.
