</div>The macs have a funny BIOS that has a persistent memory. So it will<br>
remember where you booted from, and a few other things. If this BIOS<br>
gets confused and stores its confusion in persistent mem, you get<br>
exactly what you are seeing.<br>
<br>
Removing the batteries resets this memory.<br>
<br>
In Mac parlance, resetting this memory is known as "resetting the<br>
PRAM" (or maybe PROM). There is a key combination -- different between<br>
mac models -- that does this. Add the exact model of your mac to the<br>
search below...<br>
