Some of the features of some SPEA drivers (e.g. BigFocus12 or BigMicro) can only be used with board combinations.
SPEA offers detailled information about combining boards in an additional publication titled 'Dual Screen Configurations' (also available via the SPEA Mailbox). Further details can be found in the README file supplied with this board.
There are however, some basic rules which you must know when installing 2 graphics boards in one system.
You may not simultaneously use 2 active VGA boards in one system.
If two VGA boards or parts (e.g. boards with an extra VGA part or motherboard with VGA chip) are combined in one system, one of them MUST be deactivated and be set-up as the secondary board, or switched off completely.
Note for PCI users: the autoconfiguration software incorporated on most PCI version 2.0 systems should automatically deactivate any supplementary VGA boards found in PCI slots. Check the documentation of your motherboard manufacturer to make sure that your system can support 2xVGA in PCI slots (not all systems can do this) if you are combining 2 PCI VGA boards.
Note for VL users: some motherboards define the first board found as master, the next board as slave. If the board with the deactivated VGA part is defined as master then you will have to change the physical order of the boards to be able to use the combination. The V7-MIRAGE P-64 VL can not be installed as a secondary board in a system.
