OF 1.0.5 works with vanilla 9660 disks.  OF 3 (used to) require HFS 
or hybrid disks.  It took some work to come up with a hybrid format 
that would work with both.

No.  DIR works in OF 1.0.5.  I suspect there may be disks you can 
boot from that you can't DIR, but I can't prove it.  Well, I know you 
can't DIR a HFS partition that you can boot MacOS from, but that's 
not what I mean.

It seems pretty safe to assume that if you can see a file with DIR 
you can load it with the boot command.

Every time I deal with OF I feel like I'm walking a minefield.  I 
can't always see the footprints from the last time I walked the same 
field.
