OK, I give up. I was suffering of a local blindness ;)

But yet another silly question: Is there any chance it will work if you
have two _different_ SCSI cards in single computer?

<groan> You would have to ask that. Unfortunately, there's no way to predict
what the system BIOS will do. It depends on the order that each of the BIOS
extensions on the host adapters are executed by the system BIOS, and there's no
standard for this at all. Some system BIOS identify all the BIOS extensions on
peripheral cards and then sort them by increasing size, others by decreasing
size, and some simply by slot order. Then they must be copied to low memory
for execution. Whichever BIOS extension gets control first will generally
probe for devices and then install the disks the BIOS understands by hooking
the appropriate interrupt(s). Note also that once a BIOS extension executes it
can shrink itself back to a smaller resident size, so fitting everything
sometimes depends on the recognition order. It's not pretty at all. Certin
combinations of cards can only be used in a specific order in certain
motherboards because of this. It's a tech support nightmare.
