Re: El Torito Dual Boot.

[Andrei Warkentin]

Take anything I say with a grain of salt, but...

AFA I understand, if the disk is an HFS or hybrid HFS/ISO,  
OpenFirmware scans it for a "blessed" folder, and looks for a file  
with a resource type "tbxi", which it then runs. This is usually  
(always?) a bootinfo script that specifies further actions. I do not  
know if it is possible to boot off straight ISO9660 disks from  
OpenFirmware - maybe it just looks for a file called bootinfo or  
bootscript?
Mkisofs can be used to master hybrid HFS/ISO disks that can boot on  
Pmacs. On OS X, one would use the native "hdimage" and "bless"  
utilities.
