Okay I will.  What state would you like my msdos partition-map to be in 
at the time I test -- EFI Protective[1], or a hybrid MBR/GPT[2], or 
something else?  Would you like me just to run the boot info script for 
you, or also to say what happens when I boot from that state?  If I boot 
from that state to test, is it enough for me to hold alt/option[3] to 
choose booting the MBR, or should I reset the NVRAM to test (in which 
case I may or may not have to hold alt/option anyway to choose MBR boot)?

[1] I think this is the Apple default but I've changed it so much since 
buying my machine that I'm not sure.  I also won't know what state 
Apple's Windows-installing Boot Camp GUI puts the disk/NVRAM in because 
I haven't done that and won't do that.

[2] which I'm using right now so that I can boot via PBR

[3] Holding alt/option while booting, in Apple's firmware, lets you pick 
what to boot amongst the options it can detect.
