I work in a computer lab at a school. In the lab we have LC 550, LC 575... old dirt stuff. Well I've been trying to reinstall the OS... I downloaded OS 7.5.3, and I downloaded the OS 7.5.3 Network Access Disk. Well I copied the 7.5.3 install files to the 140mb hard drive, along with the Network Access System Folder. The problem I'm having is that the Install loads but asks for the setup disks? Anything I'm doing wrong? Or any pointers. I really need to get some of these computers back up. Popping in the striaght disk for real setup disks I have dont work. Says model and version incompatibility. Anyways thanx.

Easiest way to install 7.5.x is to make disk images (.img, not .dmg of course) of the install diskettes, or, if you downloaded them to begin with, simply put them on a server in such a way that the individual Mac workstations can access and mount them all using the 7.5.x version of DiskCopy.
OR you could just make one System Folder (using "install for any Mac" just in case), tweak it the way you want it, then copy that whole System Folder to each machine over the network, throw the old one in the trash, and reboot. (might want to bless the new Sys Folder by pulling Finder out onto Desktop then tossing it back in first).

By "this" you mean copy the System Folder to the other Macs on the network?
OK, after you've got the System Folder the way you want it, insert a bootable CD (or any bootable media) and boot that Mac from it, then duplicate the System Folder in the Finder. Reboot normally and copy the Copy to the other Macs on the network.

the only reason the extenstions would be in use, is if you are copying the system that you are booted from (the active System Folder) One way to do this, is boot from a startup floppy or other external drive, or a bootable CD, and duplicate your system folder. then Unbless the System folder that you want to use on other systems (move either the Finder or the System file to a separate folder (your choice) inside that system folder, just so you know where it is. Reboot to the main drive, now you'll have 2 System Folders (one is disabled, should not have the System icon across the folder) copy that one to the system where needed, then move that crucial file back to its place in the main System Folder, close that System Folder, you should now have a good "blessed" system ready to go. You should see the System Folder icon appear, that indicates it is now 'blessed'

sadly i think is computer lab is seriously screwed... i wouldnt even call it a lab. but uh.... everytime i try to do a network install.. the network machine i use crashes.. its apple talk... like token ring.. stuff... none of them have atleast 10mbit... its pretty sad.. each time i follow your guys directions the systems freeze... i think the kids have really beat these machines honestly

You really don't want to run an installer over the network if it's using the old localtalk. way,way slow I never had much luck with installing over it, 250 Kbit/sec, if I remember right.
You're better off to do installs at each system individually.

these LC550's have external drives.. and 575 have internal i think... pop in the desk with a boot disc... freeze.... some of the internal cdroms have tape over 'em saying "DONT USE INTERNAL CDROM, EXTERNAL ONLY". i tried to burn an OS 8 for'em... but they dont recognize the format... i burned it on OSX with Toast 6... but oh well.. im pretty much done with this lab... and i start a new job monday.. so i dont really care.. much now.
