This is the dump I got from the MacOS X CD.  Looks like it's like other 
Apple CDs I've looked at in that some of the fields aren't exactly what 
they should be - disk size for instance. Map Entries #4 and #8 are 
different; I haven't seen anything like that before.  It looks to me like 
the CD is relying on the Start Manager to get booted?  As I understand it 
this means the ROM (or OF) is looking for the HFS partition marked 
bootable and loading something that it thinks is MacOS from that 
partition.  Does anyone know if this would load and execute NetBSD if it 
appeared to be in the proper place in an HFS partition?
