Two identical SoundBlaster PCI cards in a QNX4 box?

I need to record four mono channels of audio under QNX4. Is it possible to
have two identical SoundBlaster PCI cards in an x86 QNX4 box? ( I know that
I will need to use the unsupported ALSA drivers for SB.)

It seems that using two identical cards is a “challenge” under Windows, if
not impossible, so that is why I am asking…

Why identical cards? Because we need to produce these boxes in moderate
volume, and requiring different cards would be a headache when it comes to
service, spare parts, etc.

Please be advised that I am brand new to audio programming, sound cards, and

Also, how would any of you suggest recording four audio channels under QNX4?
