Macintosh BootDisks

Posted on 1998-12-08

How do I go about making a Macintosh boot disk that can take up more than 1.3 megabytes?  I wouldn't even mind making a RAM Disk, and copying files from two system disk to the RAM Disk, and use it like a system Drive.  Is this possible?

The reason I want to be able to do this is because if I can boot up with a boot disk with Networking support, I can just copy a system from another computer.

In particular, one of the schools that I support has mostly LC 475 computers.  I tried removing different things from the boot disk, but when I remove things like finder, or anything like that, it just ejects the disk and reboots.

On a floppy you cant..its just not possible.

Yes but make sure you dont shut down as you will loose the contents of the ramdisk. You CAN boot off it and as long as youve got enough ram you can load a networkable system folder into it.

Lastly you cannot remove anything like the finder or system file from a boot disk as those ARE the files that have to run. They ARE the boot process remove them and its just not going to boot.

How do I load files into the RAM Disk on Startup?  I know in DOS, you can simply use a compressed .cab, or .zip file, and uncompress into the RAM Disk.  Macs don't allow Batch files, or scripting of any kind for this task, do they?

you would create a RamDisk on your desktop in the memory controll panel. Upon restart it will appear there. Simply drag the files you want into the ram disk. In this case a system folder. Go into the Startup Disk Control Panel and select the ram disk as your startup disk. Restart. The computer will restart off the ram disk. Easy as that. Remember...its a mac...drag n drop..=)
