Alphastations 255 Multiheaded

Hello osf-managers,

We have Alphastations 255, 233Mhz and 300Mhz configurations with Factory
installed software Unix 4.0b. The system installation goes through
successfully but as the system initialises the 3 graphics controllers and
attempts to start the CDE environment the system crashes and starts
dumping.

These Alphastations come with 3 X Digital TGA2 graphics controllers (part
# PBXGB-AA/CA PCI graphics cards).
Firmware levels:
SRM: 6.4-2
OSF-Palcode X1.46-2
Serial Rom ver 1.12
Diag Rom ver 1.5

While the system is booting, the 3 graphics cards are recognised by the
kernel. We tried 3 different approaches: 1. With one card the system
boots fine. 2. With 2 cards the system also boots fine but only one of
the screens display the CDE the other one stays blank. 3. With 3 Cards
the system panics with a kernel error message.

Do you know of any problems regarding this configuration?
Is it even supported with 3 graphics cards?
Are there any patches that should be installed for this problem?
Perhaps there is a file which needs to be edited in single user mode for
it to support more screens???

Looking forward to your responses.
Paulo
