Why can't Fedora do this? I've got 2Gb of physical RAM on this box. I
know that slax can be booted into a little as 256MB of RAM to free up
the optical drive, so I'm sure that Fedora can fit in my 2GB.

You can create a RAM disk, and copy files over to it. But it tends
to work out better to use the memory for buffers and disk cache
instead when you are using a reasonably fast hard drive. (Optical
drives are another story - they are MUCH slower.)

The thing to remember is that most CP/M systems were run from floppy
disks. They also had to do a lot of swapping in and out because the
processors could only directly address 64K of RAM. CP/M+ could swap
pages in and out if your hardware supported it, but you were still
limited to 64K mapped in at one time.

If you want a system that boots up fast, you have the option of
suspend to RAM or suspend to disk. There are advantages and
disadvantages to both, but if they work on your system, they can get
you to a working desktop in a short time.
