- The only solution I know of is to create a RAM Disk and put a minimal
- system folder there (make aliases for the noncritical stuff, pointing
- to the hard disk version), and make the RAM disk your startup disk.
- And, never shut down, only sleep or restart. Keep a backup system
- folder on your hard disk. Now you get two boot chances, one with the
- RAM disk and another with your main disk. This is also good for
- improving battery life, cutting down on disk accesses on the system
- folder. The disadvantage is it takes up memory, you will probably
- need 6-8M to use a RAM disk system folder effectively. I managed to get
- one running with 1M free memory left on my 4M 210, and will switch to
- this setup permanently when I get more memory (soon). I am not
- buying a dock or a floppy, I have another Mac I can up/download from
- via appletalk.
-
- Now suppose my disk crashes and needs reformatting. Can I do all this
- from my RAM disk?
