Sonnet doesn't want you to see any software, doesn't want you to have any settings you can change. There are no dip switches, and no jumpers. Sonnet wants you to plug the card in and just have it work. The XLR8 card also works right out of the box. Each card performed superbly in our test system, a UMAX S900.
Installation is simple.
Run the software, remove the old processor card, and plug in the new one. If your system has a CUDA button, it's a good idea to press it, but that shouldn't be necessary. We prefer CD distribution. You do need a screwdriver, and an antistatic wrist strap is a good idea too. XLR8 thoughtfully provides both in its package.
