my test was successfull..
i copied the 9.1 firewire extensions from mac os 9.1 to mac os 9.02
and now i have my firewire drive working under mac os 9.02
just a heads up!
it works!
i will attach the firewire extensions here..
the two extensions are:
"Firewire enabler" v2.7
"Firewire support" v2.7
i will see if the same can work for mac os 8.6 next..
SUCCESS!
8.6 confirmed works with these v2.7 firewire extensions as well!
great!
the extensions disk image ive attached includes the 8.6, 9.02, + 9.1 fw extensions
for the improved firewire mountability with modern drives, overwrite your extensions with the 9.1 versions!
