VTSERVER booting

[Philipp Hachtmann]

Hi again,

after removing all other cards from my 11/23+ my serial console seems to 
work error-free.

Now I can bootstrap the copy utility which comes with vtserver. I can 
also copy something onto a formatted diskette. When I copy from diskette 
to the virtual tape, the copying seems to ignore the disk's end... is 
that correct? I simply tried to copy the copy binary itself to an rx02 
and boot that. Did not work. I verified the disk contents i put on it - 
they're ok....

I also have tried the 2.11BSD stub which came with vtserver (boot.dd, 
disklabel etc). Boot.dd gave me only A LOT of:
> Trap in Boot,illegal instruction at loc Trap in Boot,illegal instruction at loc Trap [...]
Continues several screens and then the cpu hangs (still running) after 
outputting
> ....instruction at loc Trap in Boot,illegaløQøQ`êWfª


What have I done wrong?
Where can I get more information about different boot roms, 
bootstrapping the 11/23+ and my RX02 drive (nothing on bitsavers...!?!)?
What does the (which one?) boot prom put where and where does it start 
execution etc.?
There must be cool docs which I don't know yet....


Regards,
Philipp :-)
