Hi Jerome,

I'm actually not that familiar with OS 9.  On OS X, there is a system  
utility called 'bless' [see man bless].  Essentially, this needs to be  
used to set the location of the "System Folder" in the HFS boot block.   
I don't know what the equivalent is for mac os 9.

Why don't you mount the vm's disk image and do bless -info on it and  
post the results?  Here is how you would do that:

1.  Make sure Mom is not running and open a terminal
2.  hdiutil attach <path_to_your_vm>/disk0.dmg
3.  bless -info /Volumes/<name_of_your_vms_hard_disk_volume>

Perhaps someone knows more about 'bless', but I wouldn't mess with it  
any further at the moment.  You could end up accidentally making your  
host system unbootable :-)

Here is an example for my vm:

------------------------------------------------------------------------

tedbook:~ ted$ hdiutil attach ~/vms/rel/disk0.dmg

/dev/disk3              Apple_partition_scheme

/dev/disk3s2            Apple_HFS                        
/Volumes/untitled
tedbook:~ ted$ bless -info /Volumes/untitled/
finderinfo[0]:     30 => Blessed System Folder is  
/Volumes/untitled/System Folder
finderinfo[1]:      0 => No Startup App folder (ignored anyway)
finderinfo[2]:      0 => Open-folder linked list empty
finderinfo[3]:     30 => OS 9 blessed folder is  
/Volumes/untitled/System Folder
finderinfo[4]:      0 => Unused field unset
finderinfo[5]:      0 => No OS 9 + X blessed X folder
64-bit VSDB volume id:  0x1C49D982A548D68C
------------------------------------------------------------------------

You can see that the System Folder is blessed on my vm.  That is  
because I did a proper install, and somewhere along the way the os9  
installation blessed it's virtual disk.

Anyone know how to safely 'bless' a disk image?  I'll try to find out  
how and get back to you.
