Humm, I should have asked first if thats a ppc mac, or an intel mac. If you've downloaded an intelish (ix86) .iso, it won't work on a ppc mac, different cpu's don't understand each others languages. In any event, that os should have something like an 'ls -l' command that you can execute from a shell in that directory, and that should spit out the size of the .iso in bytes, lots of them. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
