I would look in, Sys/Lib/Extentions, and, relate, the, specific files, that, I deleted, but I have, deleted, them all, on, all, my up and running, eMacs. Like, I said, they all work, fine, without, the ones, I, have deleted, and I would go so far, as to say the system is more responsive, on booting, and, "snappier" in every app that I use. (Me, Naval, trained, electrian) (first, part oif training, how to design, electronic, and, electric, circuitry) (and you must do this in a short time period, each module is timed, so I became good at it, top three in my class) So, I, see, in my, head, that, poor, HD, read, arm, sweeping, over, the disk, and, having, to, avoid, the Intel, stuff, that it, will, never read, and, it, annoys, me. Classically, to make A perfect install DVD would be quite, A, daunting, task, and most software companys, would like to keep their good program, writers, without, making them rich. There, is, A Leopard, Security, PDF, that, notes, the, uselessness of unused, software, on, A harddrive. Are you familiar, with it? if not I'll post it, or google Leopard Security to find it. It's on Apple's data base. I, would just like to get rid of the rest of the files not used, by the Power PC platform, while not causing A crash! Please let me know if you, come up with anything, thanks.
