BM38 SP5 on NW6.5 SP6

We had customized the error, login and logout pages some time ago and it
was all fine. I recently noticed that we still get the custom error
pages on what appears to be the old 1959 port pointing to
SYS:ETC\PROXY\DATA folder.

The login page appears, however, at https://192.168.1.4:51443/BM-Login
and uses the Novell BM login page.

Question is, how does one now customize the login and logout pages.
Since I have no apache web servers running, I imagine this is part of
the mini-web server as well, but what folder is it pointing to? Or if it
still points to the same folder, what name should the login page take?

Thanks,
Ken
