Hello Camiel,
did you update the CVS?
I updated the code few mins ago, but now the OpenVMS 8.3 installation
seems to loop shortly after the OpenVMS banner.
These are the memory addresses: 187868 | ffffffff801aa170
285915 | ffffffff80012208
Before the latest update (when I reported the format error), 1 min
after the openvms banner, I had "Installing some known required
files..." message, but in this case, after about 10 mins, nothing
happens.
regards,
fausto
