Yes, BIOS is set to boot of CD.  It asks me to choose another boot 
method or insert bootable media.  As I mentioned, it just doesn't work 
for 64 bit iso, a friend's 386 iso boots, but doesn't allow me to rescue 
the system because of the incompatibility.  This same 64 bit iso disk 
rescued my other 64 bit system.  I even made another copy, thinking it 
had somehow turned into a coaster in between systems.  No luck.
