- I have a IIci with 20 MB of RAM. I would like to try running the OS on the
- RAM disk, but I'm confused: The RAM disk is an INIT in the system folder -
- it starts up when the OS starts up. By changing the startup to the RAM
- disk (which, to my knowledge, starts up *after* the OS), how does the RAM disk
- INIT even start up?
-
- Also, what RAM disk program will start up the OS? I've got a copy of RamDisk+
- 3.0.1, but it gives me an 'out of memory' feature when I try to start up
- with it (pretty odd when I have 20 megs RAM).
