[Kayvan Sylvan <kayvan@xxxxxxxxx>]

Thanks very much for the replies.

We would like to lend some help with trying to implement the protection 
registers.

What is your advice on how to proceed?

Right for me.

Not yet.  The HP-UX efi loader crashes very early.  This is currently
blocking.  I need either help from HP *or* time to investigate.

Most of them :-)

Protection registers.  I think that's almost it.

OpenVMS now works on Xen/ia64.  There are still a few issues however (e.g. UP
only).

Protection registers.

You're welcome!
