PC Setup 1.6.3: Where Is It?

I just got my new Power Macintosh G3. I want to put in my DOS card -- the Read Me on the Power Macintosh G3 indicates I need PC Setup 1.6.3. I can't find this in the software updates. Where do I find 1.6.3?
PC Setup 1.6.3 has been superseded by PC Setup 1.6.4. PC Setup 1.6.4 is available from Apple Software Update sites.

These articles can help you locate the software update mentioned here:
