3.4 Multihead
Support
The minimum firmware version for multihead 3Dlabs OXYGEN VX1 PCI
graphics controller support on AlphaServer and AlphaStation DS10, DS10L,
DS20E, and ES40 is V5.9. The Alpha system firmware must be updated to
support 3Dlabs OXYGEN VX1 PCI graphics controllers. Once the Alpha system
firmware has been updated, multiple 3Dlabs OXYGEN VX1 PCI graphics
controllers may reside in the same system.
___________________________ Note ____________________________
Only one 3Dlabs OXYGEN VX1 PCI graphics controller will be used for the VGA console;
it must be placed on the primary PCI bus.
____________________________________________________________
The card in the lowest numbered slot will usually be selected to be the VGA
console. See your workstation or server user manual to determine slot
numbering. The maximum number of 3Dlabs OXYGEN VX1 PCI graphics
controllers supported by software is 16, but please see the following section for
limitations.
3.4.1
Multihead Restrictions and Limitations
The 3Dlabs OXYGEN VX1 PCI graphics controller is not supported in
conjunction with any other non-3Dlabs OXYGEN VX1 PCI graphics controller
residing in the same system.
All 3Dlabs OXYGEN VX1 PCI graphics controllers in a single system must have
the same color depth. The supported number and configuration of multiple
3Dlabs OXYGEN VX1 PCI graphics controllers varies by platform. Other
documentation shipped with your workstation or server will outline specific
limitations on the actual number and the configuration of multihead support.
