I hoped that might be it.  I sure didn't want to deal with undocumented calls!

Thank you for your reply, Andy. 
You run a good forum, which supports Flash Magic quite well.

I am writing my own boot loader for a P89C668, and I would like for it to be backwards compatible with the Flash Magic tool. 

I noticed that Flash Magic has the capability to reset the P89C668.  I also noticed that the data sheet description of the supported ISP hex record commands does not include reset. 

So how do you perform a chip reset?  Are you making use of some of the undocumented ISP records and subfunctions?  And if so, which ones do I need to support in order to run Flash Magic?
