I think some graphic cards support multihead, other do not. You'll
have to check each specific card.
Note the PCI slot nearest the motherboard uses shared interrupts.
OpenVMS does not support the use of *any* card in this slot, limiting
the number of PCI slots in the system.

| 1981.2 | Xwindow SUpport | SWAM1::POIANI_MI | | Wed May 21 1997 20:28 | 2 |
| does the VMS xwindowing environment support Multihead similar to UNIX?

| 1981.3 | 3 heads, yes | WRKSYS::BCLARK | I have dyslexia of the fingers | Thu May 22 1997 09:15 | 42 |
| Back in late August last year, VMS engineering and Workstation's
PostFRS Team qualified a 3 head configuration for Alphastation 255
running VMS. You should find that detail in the SOC. I recall working
with the product manager to ensure the SOC was accurately updated.
In summary this is what worked:
(2) TGA2 aka Powerstorm 3D30 aka PBXGB-AA configurated with the VGA
DISabled.
(1) S3trio aka Powerstorm 3D10 aka PB2GA-JA configured in the "shared
slot" as the console.
At the time, VMS was at V6.2-1H3 which required a patch to the S3
driver:
BULOVA::DISK$SYSKITS:[PUBLIC.DECWINDOWS.SERVER]DECW$SERVER_DDX_S3.EXE;2
489 29-AUG-1996 09:37:19.00
I was told at that time the corrected driver would be included
in V7.1. I have not verified that.
Otehr details include:
LX3+ @300Mhz
SRM Console V6.2-2
Palcode VMS V5.56-2 OSF X1.46-2
Serial ROM V1.11
Diag ROM V1.5
Memory 64Mb
system disk RZ26F 1Q0A
VMS Version 6.2-1H3
Open 3D version 3.4
Hope this helps. By the way, while working an IPMT case recently, we
effectively qualified a 3 headed AS255 running Unix. This will be added
into the SOC shortly. In the Unix case, 3 heads (all 3D30) without
Open3D (but including a new tga.o driver) under Unix 3.2G is the minimum
configuration which will be supported.

| 1981.4 | DECwindows 5760.*; Not Fully Supported by CDE | XDELTA::HOFFMAN | Steve, OpenVMS Engineering | Thu May 22 1997 10:22 | 19 |
| : Does the 255 support multihead under VMS?
The official definition of "support" translates as "check the SPD". And
in this particular case, it's not really OpenVMS that is central to the
question, it's DECwindows...
As for the practical answer, there are various double- and triple-headed
AlphaStation 255 systems here in OpenVMS engineering -- all configurations
I am aware of here are using multiple PowerStorm 3D30 (TGA2; PBXGB-AA)
graphics controllers. (Other controllers may also be possible, but folks
seemed to copy the orders off one AlphaStation 255 system order. :-)
I posted a note describing how to set up a multi-headed system under
OpenVMS DECwindows over in the DECwindows conference a while back.
I had some problems getting CDE to work as one might expect on this
configuration, but the Motif interface (which I personally prefer to
CDE in any event) works just fine multi-headed.
