the files should detect the alti-vec automatically. The difference between a Yikes! and a B&W is the firmware it has. That's all. Once you upgrade it, it will be just a Yikes! no more is needed unless it disables the cache by default on the card's firmware itself.

If anything, you need to just do the firmware update I provided the link to at minimum, otherwise it won't boot. Apple Just disabled the G3 functions because they were going to use the Yikes! to introduce the G4 and wanted to use the Yikes! to stall till the AGP Machine was finished.

Other than that? Nothing. Just do the firmware update, drop it in. if you need the Cache to run (like if it is disabled) then go ahead and use Sonnet's enabler (if they have one)
