I looked and the directory wasn't there - let me confirm this tonight when I've got access to the machine again.
It's running TCP/IP Services 5.1 - could this be an issue?

This is why I like HECNET - instant answers to esoteric questions :)
Which reminds me - anyone have any tips on how to get remote XDM going on OpenVMS VAX 7.3? I can't find the setup files.
Basically, I want to point an XDM client on the laptop at the XDM server on the SIMH machine and get a graphical session that way.

As for AUTOGEN, I recently upgrade CHIMPY from 256 MB to 1 GB and it just recognized the RAM automagically? Am I missing something?
What is Chimpy?
I upgraded SIGGE from 256M to 1.25G a few weeks ago, and I had to run an AUTOGEN before the memory was recognized by the system (as shown by SHOW MEMORY inside VMS). The hardware saw the memory immediately, but VMS did not want to have anything to do with it before the autogen.
Gregg: I'm running the emulator on a Dell laptop, Core 2 Duo processory, Ubuntu Desktop + Oracle VirtualBox + Ubuntu Server. As for the Alpha emu, it's not exactly scarce: you can just google for PersonalAlpha and get a Windows version that's kinda restricted but functional.
So Chimpy is an emulator? Emulating which model?
Johnny
No CHIMPY is a physical AlphaServer 800, and VMS on it recognised the memory upgrade automagically.

DELLVX is the emulated contraption - I wanted to be able to talk from the main host machine to the SIMH box, so I run SIMH in a VM on the main host, viz:
DELLHOST - Physical Dell laptop, running Ubuntu Desktop 10.04), runs Oracle VirtualBox:
DELLVM - Virtualised Oracle VirtualBox VM running Ubuntu Server 10.04, runs SIMH:
DELLVX - Emulated VAX running OpenVMS 7.3
This way I can connect from DELLHOST to DELLVX by network, the DELLVM is quite lightweight as it runs Ubuntu Server (like 30-40 megs overhead).

That's a difference between alpha and vax vms, on alpha physical_pages is not required.
I can't remember. Is there some other parameter that do the same thing on the Alpha, or will it dynamically detect and manage this on boot?
About 7.3-1, yes that is obviously a type since there is no such vms version for neither vax nor ia64.
Thanks. I was wondering if I had missed something.
The last vaxes, the 7000 and 10000 series supported 4 GB physical memory. I wasn't aware of more than 32 address bits in the hardware.
Well, earlier VAXen only support 30 physical address bits. The NVAX supports either 30 or 34 physical address bits (software selectable which mode it should operate in). How many address pins actually were brought out from the CPU chip, as well as out from the CPU card, I don't know, which is why I said "in theory".
It might be that the 7000 and 10000 only supported a max of 4 GB, but that would be a restriction of the physical design in that case. The extension of the VAX MMU done for the NVAX brought the size of an address up to 34 bits.

The address field in a PTE can be either 21 bits (traditional) or 25 bits (extended). Add to that, the address within the page (9 bits), and you'll end up with either 30 bits, or 34 bits of physical addresses.
32 bit physical addresses have never existed on a VAX.

As for memory, VMS (on VAX) supports up to (in theory atleast) 16G of
physical memory. However, that requires the extended memory mode PTEs,
which only came with NVAX, so no luck with simh.
The "older" layout supports a max of 1G, but I think all architectures
machines split that into 512M of RAM and 512M for I/O space.
Oh, and when you add memory, you need to run an AUTOGEN afterwards, to
change a bunch of parameters to the new hardware config (whould be
obvious ;-) ).

That is one of the things AUTOGEN will do for you, yes. :-)
As always, you do not need to run AUTOGEN, you can always trim the parameters yourself if you want to. After all, that is all that AUTOGEN do as well.
